+        <p>Deployment Tools Foundation is a rich set of .NET class libraries and
+        related resources that together bring the Windows deployment platform
+        technologies into the .NET world. It is designed to greatly simplify
+        deployment-related development tasks while still exposing the complete
+        functionality of the underlying technology.</p>
+        
+        <p>The primary focus of DTF is to provide a foundation for development of
+        various kinds of tools to support deployment throughout the product
+        lifecycle, including setup authoring, building, analysis, debugging, and
+        testing tools. In addition to tools, DTF can also be useful for install-time
+        activities such as setup bootstrappers, external UI, and custom actions,
+        and for application run-time activities that need to access the deployment
+        platform.</p>

+            <h3>Getting progress</h3>
+            Most cabinet operation methods have an overload that allows you to specify a event handler
+            for receiving <a href="DTFAPI.chm::/html/T_Microsoft_Deployment_Compression_ArchiveProgressEventArgs.htm">archive
+            progress events</a>. The <a href="cabpack.htm">XPack sample</a>

+            <p><br/></p>
+            <h3>Stream-based compression</h3>
+            The CabEngine class contains static methods for performing compression/decompression operations directly
+            on any kind of Stream. However these methods are more difficult to use, since the caller must implement a
+            <a href="DTFAPI.chm::/html/T_Microsoft_Deployment_Compression_ArchiveFileStreamContext.htm">stream context</a>
+            that provides the file metadata which would otherwise have been provided by the filesystem. The CabInfo class
+            uses the CabEngine class with FileStreams to provide the more traditional file-based interface.

+            <p>This is a managed library that provides the ability to 
+            create and extract cabinet files. It uses cabinet.dll (present on all versions of Windows) 
+            to do the actual compression/decompression. It provides access to nearly all 
+            cabinet capabilities, including spanning of multiple cab files. It even has support for
+            preserving directory structures and UTF8 paths.</p>
+            <p>There are two ways to use the library. <a href="ms-its:MMLRef.chm::/Microsoft.Cab.CabinetInfo.html">CabinetInfo</a> 
+            and <a href="ms-its:MMLRef.chm::/Microsoft.Cab.CabinetFileInfo.html">CabinetFileInfo</a>
+            (similar to DirectoryInfo and FileInfo respectively) 
+            provide high-level object-oriented methods for doing common file-based cabinet creation and 
+            extraction tasks. On the other hand, the <a href="ms-its:MMLRef.chm::/Microsoft.Cab.Cabinet.html">Cabinet</a>
+            class provides low-level access to all
+            functionality, and operates completely in terms of .NET Streams. The previous two classes use
+            the Cabinet class to do all the actual work.</p>
+            <p>There are also two ways to build the library. 
+            Compiling it normally will produce the fully functional 
+            library in the <a href="ms-its:MMLRef.chm::/Microsoft.Cab.html">Microsoft.Cab</a>
+            namespace, while compiling it with the <tt>/D:CABMINIMAL 
+            /D:CABEXTRACTONLY</tt> flags will create a compact assembly with only the core extraction 
+            functionality, in the <a href="ms-its:MMLRef.chm::/Microsoft.Cab.MiniExtract.html">Microsoft.Cab.MiniExtract</a>
+            namespace.</p>
+            <p>The cabinet library interops with native cabinet APIs which use the 'cdecl'
+            calling-convention. When building against .NET Framework versions before 2.0,
+            this library requires a special post-build step to process the UnmanagedFunctionPointerAttribute.
+            If you use this code in another assembly, don't forget to run <a href="augmentil.htm">AugmentIL</a>
+            on it to fix the delegate calling-conventions, otherwise you will encounter a
+            NullReferenceException when attempting to call the cabinet APIs. When building against
+            .NET Framework version 2.0 or later, the UnmanagedFunctionPointerAttribute.cs source file
+            should be omitted.</p>

+                </div>
+                <div id="nstext">
+            <p>The custom action proxy allows an MSI developer to write
+            custom actions in managed code, while maintaing all the advantages of type 1
+            DLL custom actions including full access to installer state, properties,
+            and the session database.</p>
+            <p>There are generally four problems that needed to be 
+            solved in order to create a type 1 custom action in managed code:</p>
+            <ol>
+            <li><p><strong>Exporting the CA function as a native entry point callable by 
+            MSI:</strong> The Windows Installer engine expects to call a LoadLibrary and
+            GetProcAddress on the custom action DLL, so an unmanaged DLL needs to implement
+            the function that is initially called by MSI and ultimately returns the result.
+            This function acts as a proxy to relay the custom action call into the
+            managed custom action assembly, and relay the result back to the caller. </p>
+            <li><strong>Providing supporting assemblies without 
+            requiring them to be installed as files:</strong> If a DLL custom 
+            action runs before the product's files are installed, then it is difficult 
+            to provide any supporting files, because of the way the CA DLL is singly 
+            extracted and executed from a temp file. (This can be a problem for
+            unmanaged CAs as well.) With managed custom actions we have already hit
+            that problem since both the CA assembly  and the MSI wrapper assembly
+            need to be loaded. To solve this, the proxy DLL carries an appended
+            cab package. When invoked, it will extract all contents of the
+            cab package to a temporary working directory. This way the cab package can
+            carry any arbitrary dependencies the custom action may require.</li>
+            <li><p><strong>Hosting and configuring the Common Language Runtime:</strong>
+            In order to invoke a method in a managed assembly from a previously
+            unmanaged process, the CLR needs to be "hosted". This involves choosing
+            the correct version of the .NET Framework to use out of the available
+            version(s) on the system, binding that version to the current process, and
+            configuring it to load assemblies from the temporary working directory.</p>
+            <li><p><strong>Converting the integer session handle into a 
+            Session object:</strong> The <a href="">Session</a> class in the managed
+            wrapper library has a constructor which takes an integer session handle as 
+            its parameter. So the proxy simply instantiates this object before
+            calling the real CA function.</p>
+            </ol>
+            <p>The unmanaged CAPack module, when used in combination with the managed proxy in
+                the
+            Microsoft.WindowsInstaller assembly, accomplishes the tasks above to enable
+            fully-functional managed DLL custom actions.</p>

+            <h3>About handles</h3>
+            <p>Handle objects (Database, View, Record, SummaryInfo, Session) will remain open until
+            they are explicitly closed or until the objects are collected by the GC. So for the tightest
+            code, handle objects should be explicitly closed when they are no longer needed,
+            since closing them can release significant resources, and too many unnecessary
+            open handles can degrade performance. This is especially important within a loop
+            construct: for example when iterating over all the Records in a table, it is much cleaner
+            and faster to close each Record after it is used.</p>
+            <p>The handle classes in the managed library all extend the
+            <a href="DTFAPI.chm::/html/T_Microsoft_Deployment_WindowsInstaller_InstallerHandle.htm">InstallerHandle</a>
+            class, which implements the IDisposable interface. This makes them easily managed with C#'s
+            using statement. Alternatively, they can be closed in a finally block.</p>
+            <p>As a general rule, <i>methods</i> in the library return new handle objects that should be managed
+            and closed by the calling code, while <i>properties</i> only return a reference to a prexisting handle
+            object.</p>
+

+            <p>There are two ways to attach a debugger to a managed custom action.</p>
+            <p><b>Attach to message-box:</b> Add some temporary code to your custom action to display a
+            message box. Then when the message box pops up at install time, you can attch your
+            debugger to that process (usually identifiable by the title of the message box).
+            Once attached, you can ensure that symbols are loaded if necessary (they will be automatically
+            loaded if PDB files were embedded in the CA assembly at build time), then set breakpoints
+            anywhere in the custom action code.</p>
+            <p><b>MMsiBreak environment variable:</b> When debugging <i>managed</i> custom actions,
+            you should use the MMsiBreak environment variable instead of MsiBreak. Set the MMsiBreak
+            variable to the custom action entrypoint name. (Remember this might be different from
+            the method name if it was overridden by the CustomActionAttribute.) When the CA proxy
+            finds a matching name, the CLR JIT-debugging dialog
+            will appear with text similar to "An exception 'Launch for user' has occurred
+            in <i>YourCustomActionName</i>." The debug break occurs after the custom
+            action assembly has been loaded, but just before custom action method is invoked.
+            Once attached, you can ensure that symbols are loaded if necessary,
+            then set breakpoints anywhere in the custom action code. Note: the MMsiBreak
+            environment variable can also accept a comma-separated list of action names, any of
+            which will cause a break when hit.</p>

+        
+        <h3>Build-time Dependencies</h3>
+        <ul>
+          <li><p><b>Visual Studio / .NET Framework</b> - Most of DTF can be built with Visual Studio 2005 &
+          .NET Framework 2.0. However, the LINQ project requires VS 2008 & .NET Framework 3.5.</p></li>
+          
+          <li><p><b>Sandcastle</b> - .NET documentation build engine from Microsoft, used to process all the XML doc-comments
+          in DTF libraries into DTFAPI.chm.
+          <a href="http://www.codeplex.com/Sandcastle/" target="_blank">(official site)</a></p></li>
+          
+          <li><p><b>Sandcastle Builder</b> - Sandcastle by itself is complex and difficult to use; this free tool
+          from Codeplex provides an easy-to-use project system around it to automate the documentation build process.
+          <a href="http://www.codeplex.com/SHFB/" target="_blank">(project link)</a></p></li>
+          
+          <li><p><b>HTML Help Workshop</b> - Tools for building HTML Help 1.x (CHM files). Used to build DTF.chm.
+          <a href="http://msdn2.microsoft.com/en-us/library/ms669985.aspx" target="_blank">(download link)</a></p></li>
+        </ul>
+        
+        <h3>Run-time Dependencies</h3>
+        <ul>
+          <li><p><b>.NET Framework</b> - Most of DTF requires .NET Framework 2.0. (.NET 1.1 is no longer supported.)
+          The only exception is the LINQ assembly which requires .NET Framework 3.5.</p></li>
+          
+          <li><p><b>Windows Installer</b> - Windows Installer introduced new APIs and capabilities with each successive
+          version. Obviously, the corresponding functionality in the managed APIs is only available when the required
+          version of the Windows Instaler (msi.dll) is installed on the system. Use the Installer.Version property
+          to easily check the currently installed MSI version. Attempting to use an API not supported by the current
+          version will result in an EntryPointNotFoundException. To check what version is required for a particular API,
+          see the documentation link to the corresponding unmanaged API in MSI.chm.</p>
+          <p>In some instances when a newer version of MSI provides an "Ex" alternative to a function, only the "Ex"
+          function is used by the managed library. This may hide some functionality that would have otherwise been
+          available on a system with an older version of MSI.</p></li>
+          
+          <li><p><b>cabinet.dll</b> - The DTF cabinet compression library uses cabinet.dll to implement the
+          low-level cabinet compression and decompression. This DLL is part of all versions of Windows, 
+          located in the system directory.</p></li>
+          
+          <li><p><b>System.IO.Compression.DeflateStream</b> - The DTF zip compression library uses this class
+          to implement the low-level zip compression and decompression. This class is part of .NET Framework
+          2.0 and later.</p></li>

+
+<ul>
+<li>Cab<ul>
+  <li>Fixed a bug that caused compressing very large files/file sets to use way too 
+  much memory. Performance on large inputs is now within a few % of native cab tools
+  (sometimes even a little faster!) for the same compression level.</li>
+</ul></li>
+
+<li>WindowsInstaller<ul>
+  <li>All the new MSI 3.0 beta APIs are wrapped, resulting in the following additions:<ul>
+    <li>New classes - Product, Patch (for accessing sourcelist and other config)</li>
+    <li>New methods on Install class - GetProducts, GetPatches, RemovePatches,
+    ApplyMultiplePatches, DetermineApplicablePatches, ExtractPatchXmlData</li>
+    <li>New enumerations - InstallContext, PatchStates, SourceType</li>
+    <li>Additional InstallProperty values</li>
+  </ul></li>
+  <li>Note, MSI 3.0 support should be considered preliminary for now,
+        as APIs (both native and managed) are subject to change.</li>
+  <li>For MSI 2.0 compatibility, developers should not use any classes or
+        methods that are marked as [MSI 3.0 beta] in the documentation.</li>
+  <li>And unrelated to 3.0, a few additional enums have been added:
+        DialogAttributes, ControlAttributes, CustomActionTypes,
+        IniFileAction, RegistryRoot, RemoveFileInstallMode,
+        ServiceControlEvents, ServiceInstallFlags, TextStyles,
+        UpgradeAttributes, LocatorType</li>
+  <li>Also made a few minor non-breaking changes to keep the library FxCop-clean.</li>
+</ul></li>
+
+<li>AugmentIL<ul>
+  <li>Added support for strongname signing and delay-signing.  AugmentIL tries to
+  locate the keyfile using the AssemblyKeyFileAttribute, or you may specify the
+  path with the new /key option.</li>
+  <li>All &quot;released&quot; assemblies will now be strongname-signed
+  (with an unofficial key).</li>
+</ul></li>
+
+<li>CAProxy<ul>
+  <li>Added support for NativeDependencies property on CustomActionAttribute.  This enables
+  custom actions to P/Invoke into native DLLs that are carried with them.</li>
+</ul></li>
+
+<li>Samples\SampleCAs<ul>
+  <li>In SampleCA2, changed MessageBox.Show(&quot;&quot;) to session.Message(User,&quot;&quot;),
+  because generally it is a bad practice for CAs to show independent UI.</li>
+  <li>Added test of CustomActionAttribute.NativeDependencies functionality.</li>
+</ul></li>
+
+<li>Samples\CabPack: added new sample<ul>
+    <li>Demonstrates &amp; tests the cab library by creating self-extracting packages</li>
+</ul></li>
+
+<li>Samples\Inventory: added new sample<ul>
+    <li>Shows a hierarchical, relational, searchable view of all of the product,
+    feature, component, file, and patch data managed by MSI, for all products
+    installed on the system.</li>

+        message and data.  This makes most exceptions extremely informative!</li>
+    <li>Added View.GetValidationErrors() method, and supporting ValidationErrorInfo
+        struct and ValidationError enum.  This wrapper for the MsiViewGetError

+            <p>
+                InstallUtil is often considered as another option for executing MSI custom actions
+                written in managed code. But in most cases it is not the best solution, for a number
+                of reasons.</p>
+            <p>
+                InstallUtil (in either InstallUtil.exe or InstallUtilLib.dll form) is a .NET Framework
+                tool for executing the System.Configuration.Installer classes that are implemented
+                in an assembly. That way the assembly can contain any special code required to install
+                itself and uninstall itself. Essentially it is the .NET replacement for COM self-registration
+                aka DllRegisterServer.</p>
+            <p>
+                Self-reg or System.Configuration.Installer is convenient for development use in
+                order to test code without creating an actual setup package, or for an IDE which
+                wants to generate self-installing code. But experienced setup developers and the
+                <a href="MSI.chm::/setup/selfreg_table.htm">Windows Installer documentation</a>
+                all agree that self-reg is a bad practice for a
+                production-quality setup. The current theory of state-of-the-art setup is that it
+                should be as data-driven as possible. That is, the setup package describes as fully
+                as possible the desired state of the system, and then the installer engine calculates
+                the necessary actions to install, uninstall, patch, etc.</p>
+            <p>
+                S.C.I encourages developers to write code for things such as registering services
+                or registering COM classes or other things which are more appropriately done using
+                built-in MSI functionality (the ServiceInstall and Registry tables). The Visual
+                Studio .NET wizards also tend to generate this kind of install code. Again, that
+                is nice for development but not good for real installations. You end up with similar
+                but slightly different code in many places for doing the same thing. And that code
+                is a black-box to the installer engine.</p>
+            <p>
+                An ideal MSI custom action is a logical extension of the setup engine, meaning it
+                is data-driven and written in a very generic way to read from existing or custom
+                tables in the MSI database, following a very similar pattern to the built-in actions.
+                This makes the CA re-usable, and makes the installation more transparent. S.C.I
+                custom actions invoked by InstallUtil cannot be data-driven because they don't have
+                full access to the install session or database. They also cannot write to the install
+                session's regular MSI log, but instead use a separate log which is bad for supportability.</p>
+            <p>
+                InstallUtil also requires that the assembly be installed before the CA is able to
+                execute. This is a problem for CAs that need to execute during the UI phase, or
+                gather information before installation. For that purpose MSI allows custom action
+                binaries to be embedded as non-installed files, but InstallUtil cannot make use
+                of those.</p>
+            <p>
+                Custom actions developed with DTF have none of the limitations of InstallUtil,
+                giving a setup developer full capabilities to write well-designed custom actions,
+                only now in managed code.

+            the current table as well as all tables under the current location in
+            the tree. While this can take a long time if there is a lot of
+            data under the current node, you can stop the search at any time with
+            the stop button. The search pauses when a match is found, but
+            clicking &quot;Find&quot; again will continue the same search from that
+            point (unless you uncheck the &quot;Continue&quot; checkbox or change

+                <div id="nstext">
+                    <p>Microsoft.WindowsInstaller.dll is a complete .NET wrapper for the
+                    Windows Installer APIs. It provides a convenient object model that is
+                    comfortable to .NET developers and still familiar to anyone who has used
+                    the MSI scripting object model.</p>
+            <h3>Notes</h3>
+            <ul>
+            <li><p>All published MSI APIs are wrapped, with the exception of four:
+            MsiGetFileSignatureInformation (because I don't know of a .NET analog for the
+            returned certificate structure), and three APIs for previewing UI dialogs.
+            Other than that, you should be able to do everything that you can
+            do via the C APIs or the COM automation interface.</p>
+            <li><p>Some parts of this code have never had a formal test 
+            pass, so use at your own risk. But much of the code is exercised daily, used 
+            by the Developer Division Sustaining Engineering team's BRIQS system to build
+            and test patches. And it has been in use by many other teams for over two
+            years now with only a few minor fixes, so it can be considered very stable.</p>
+            <li><p>Despite its official-sounding namespace, this assembly is not officially 
+            sanctioned by the Windows Installer team. But currently there are not any
+            plans for an official set of managed even in Longhorn, so I don't see a
+            conflict for now.</p></li>
+            </ul>
+            <h3>Why rewrite it?</h3>
+            <p>It is possible to access MSI's COM Automation interfaces via C# and VB.NET.
+            So why create yet another wrapper? Here are some of my reasons:</p>
+            <ul>
+            <li><p>One of the primary things I wanted to be able to do 
+            was write custom actions in C#. The automation interface was not usable in 
+            that case, because there is no way to convert the integer session handle 
+            (received as a parameter to the type 1 custom action function) into a Session 
+            automation object.</p>
+            <li><p>The automation interface does not provide a way to 
+            specify an external UI handler. Besides external UI, this is also needed 
+            to do validation.</p>
+            <li><p>The automation interface does not provide a way to 
+            explicitly close handles (other than Views). I ran into this problem when I 
+            wanted to programmatically delete a database that I'd just finished using, but 
+            couldn't because it was still open!</p>
+            <li><p>Finally, COM Automation is somewhat slower than invoking 
+            the APIs directly.</p></li>
+            </ul>

+        libraries much closer to ship-quality.</p>
+        <ul>
+            <li><p>All libraries use a new namespace hierarchy
+            under <font face="Consolas, Courier New">WixToolset.Dtf</font>.
+            The new namespace aligns with the new project name, gives all the various
+            libraries an identity that makes them obviously related to the DTF project,
+            and mostly avoids "taking over" a namespace that might be rightfully owned
+            by the platform technology owner.</p></li>
+            
+            <li><p>Assemblies are also renamed to follow namespaces.</p></li>
+            
+            <li><p>A new unified compression framework forms the basis for the new ZIP
+            library and a redesigned CAB library. Additional archive formats can
+            be plugged into the framework. The stream-based compression APIs have
+            been redesigned to be more object-oriented and easier to use. The file-based
+            APIs are mostly unchanged from the old cabinet library, although some names
+            have changed in order to fit into the new unified framework.</p></li>
+            
+            <li><p>Large parts of the WindowsInstaller library have been redesigned
+            to be more object-oriented and to better follow .NET Framework design
+            guidelines. And various APIs throughout the library have naming or other
+            changes for better consistency and to follow conventions and best
+            pratices as enforced by FxCop.</p></li>
+            
+            <li><p>The WindowsInstaller APIs no longer make any attempt to mimic the
+            MSI COM automation interfaces. The naming and object patterns in the
+            automation interfaces often conflicted with with best practices for
+            .NET Framework class libraries. Since most people start using DTF
+            without having ever experienced MSI scripting, there is little
+            reason to match the scripting object model. Making the APIs more
+            consistent with .NET conventions will make them much easier to use
+            for people already experienced with the .NET Framework.</p></li>
+            
+            <li><p>APIs in all class libraries use generics where appropriate, especially
+            the generic collection interfaces. This means .NET Framework 2.0 or later
+            is required.</p></li>
+            
+            <li><p>The FilePatch library is missing from this release. An updated
+            and redesigned file-delta library is in development.</p></li>
+        </ul>
+        
+        <h3>Other Changes</h3>
+        <ul>
+            <li><p>New MakeSfxCA tool for building managed custom action packages: In addition to
+            packaging the CA DLL and dependencies, it automatically detects managed CA methods
+            and generates corresponding unmanaged DLL entrypoints in the CA host DLL (SfxCA.dll),
+            where they are called by MSI. Previously it was necessary to either provide this
+            mapping in a CustomAction.config file, or live with the generic "ManagedCustomActionN"
+            names when authoring the CustomAction table in the MSI. For more info, see the
+            help topic on building managed custom actions.</p></li>
+            
+            <li><p>Out-of-proc managed custom action DLLs:
+            When a managed custom action runs, it normally requests a specific major
+            version of the CLR via CustomAction.config. However in the previous implementation,
+            the request could be ignored if there was already a different version of the CLR
+            loaded into the MSI process, either from a previous custom action or by some other
+            means. (The CLR doesn't allow side-by-side versions within the same process.)
+            While there have been no reports of this issue causing setup failures in practice,
+            it may be only a matter of time, as new CLR versions keep coming out.</p>
+            
+            <p>The redesigned native host for managed custom actions, SfxCA.dll, re-launches
+            itself in a separate process before loading the CLR and invoking the managed CA.
+            This ensures that the desired CLR version is always loaded, assuming it is available
+            on the system. It also sets up a named-pipe remoting channel between the two processes.
+            All session-related MSI API calls are routed through that channel, so that the
+            custom action has full access to the installer session just as if it were
+            running in-process.</p></li>
+            
+            <li><p>The new zip compression library supports nearly all features of the zip
+            file format. This includes the ZIP64 extensions for archives greater than 4GB,
+            as well as disk-spanning capabilities. Zip encryption is not supported. The zip
+            library has been tested against a variety of third-party zip tools; please
+            report any issues with incompatible packages.</p>
+            
+            <p>Currently only the basic DEFLATE compression algorithm is supported
+            (via System.IO.Compression.DeflateStream), and the compression level is not adjustable
+            when packing an archive. The zip file format has a mechanism for plugging in arbitrary
+            compression algorithms, and that capability is exposed: you can provide a Stream object
+            capable of compressing and decompressing bytes as an alternative to DeflateStream.</p></li>
+            
+            <li><p>Added support for the few APIs new in MSI 4.0:</p>
+            <ul>
+                <li><font face="Consolas, Courier New">Installer.GetPatchFileList()</font></li>
+                <li><font face="Consolas, Courier New">InstallLogModes.RMFilesInUse</font></li>
+                <li><font face="Consolas, Courier New">ComponentAttributes.DisableRegistryReflection</font></li>
+                <li><font face="Consolas, Courier New">ControlAttributes.ElevationShield</font></li>
+            </ul>&nbsp;<br /></li>
+
+            <li><p>The documentation is now built with the
+            <a href="http://msdn2.microsoft.com/en-us/vstudio/bb608422.aspx" target="_blank">Sandcastle</a> doc build engine,
+            with help from the <a href="http://www.codeplex.com/SHFB" target="_blank">Sandcastle
+            Help File Builder</a>. (The old CHM was built with NDoc.)</p></li>
+
+            <li><p>The documentation includes detailed class diagrams for the
+            WindowsInstaller and Compression namespaces.</p></li>
+
+            <li><p>WindowsInstaller API doc topics now link straight to the corresponding
+            unmanaged MSI API topics in MSDN. If you know an unmanaged MSI API you want to
+            use but don't know the managed equivalent, you can search for it and find what
+            managed APIs link to it.</p></li>
+
+            <li><p>Unit tests cover about 90% of the Compression, Compression.Zip, and
+            Compression.Cab assemblies -- basically everything except some rare
+            error-handling cases.</p></li>
+            
+            <li><p>Unit tests along with samples cover over 50% of the WindowsInstaller and
+            WindowsInstaller.Package assemblies (including custom action functionality). More
+            test cases are still being added.</p></li>
+        </ul>
+        
+        <h3>Bugfixes</h3>
+        <p>In addition to the extensive cleanup due to redesigns and unit tests, the following
+        reported bugs have been fixed:</p>
+        <ul>
+          <li><p>Managed custom actions could in rare instances fail to load with error 183
+          (directory already exists)</p></li>
+          <li><p>Timestamps of files in a cabinet could be incorrectly offset based on the timezone.
+          (This was due to a behavior change in the DateTime class between .NET 1.1 and 2.0.)</p></li>
+          <li><p>Unicode file paths for cabbed files could be handled incorrectly in some cases</p></li>
+          <li><p>Installer.DetermineApplicablePatches just didn't work</p></li>
+          <li><p>InstallPackage.ApplyPatch couldn't handle applying multiple patches to the same layout</p></li>
+        </ul>
+
+        <h3>LINQ to MSI</h3>
+        <p><i>You'll never want to write MSI SQL again!</i></p>
+        <p>Language INtegrated Query is a new feature in .NET Framework 3.5 and C# 3.0. Through
+        a combination of intuitive language syntax and powerful query operations, LINQ provides
+        a whole new level of productivity for working with data in your code. While the .NET
+        Framework 3.5 provides LINQ capability for SQL databases and XML data, now you
+        can write LINQ queries to fetch and even update data in MSI databases!</p>
+        
+        <p>Look at the following example:<br />
+        
+<pre><font face="Consolas, Courier New">    <font color="blue">var</font> actions = <font color="blue">from</font> a <font color="blue">in</font> db.InstallExecuteSequences
+                  <font color="blue">join</font> ca <font color="blue">in</font> db.CustomActions <font color="blue">on</font> a.Action <font color="blue">equals</font> ca.Action
+                  <font color="blue">where</font> ca.Type == CustomActionTypes.Dll
+                  <font color="blue">orderby</font> a.Sequence
+                  <font color="blue">select new</font> {
+                      Name = a.Action,
+                      Target = ca.Target,
+                      Sequence = a.Sequence };
+          
+    <font color="blue">foreach</font> (<font color="blue">var</font> a <font color="blue">in</font> actions)
+    {
+        Console.WriteLine(a);
+    }
+    </font></pre>
+
+        The query above gets automatically translated to MSI SQL:</p>
+        
+        <p><font face="Consolas, Courier New">&nbsp;&nbsp;&nbsp;&nbsp;SELECT `InstallExecuteSequence`.`Action`,
+        `CustomAction`.`Target`, `InstallExecuteSequence`.`Sequence` FROM `InstallExecuteSequence`, `CustomAction`
+        WHERE `InstallExecuteSequence`.Action` = `CustomAction`.`Action` ORDER BY `InstallExecuteSequence`.`Sequence`</font></p>
+        
+        <p>But the query is not executed until the <font face="Consolas, Courier New">foreach</font>
+        enumeration. Then records are fetched from the results incrementally as the enumeration progresses.
+        The objects fetched are actually of an anonymous type created there in the query with exactly
+        the desired fields. So the result of this code will be to print the Action, Target, and Sequence
+        of all Type 1 custom actions.</p>
+        
+        <p>The query functionality is currently limited by the capabilities of the MSI SQL engine. For
+        example, a query can't use <font face="Consolas, Courier New">where (ca.Type &amp;
+        CustomActionTypes.Dll) != 0</font> because the bitwise-and operator is not supported by
+        MSI SQL. The preview version of LINQ to MSI will throw an exception for cases like that, but
+        the eventual goal is to have it automatically move the data and operation outside of MSI when
+        necessary, so that any arbitrary expressions are supported in the query.</p>
+        
+        <p>Note there are no MSI handles (or <font face="Consolas, Courier New">IDisposable</font>s)
+        to worry about! Handles are all managed internally and closed deterministically. Also,
+        with the entity object model for common tables, the compiler will tell you if you get a
+        column name wrong or misspelled. The entity objects even support easy inserting, updating,
+        and deleting (not shown here).</p>
+        
+        <p>For more examples, see the LinqTest project in the source. More documentation
+        is being written.</p>
+        
+        <p>Obviously, LINQ to MSI requires .NET Framework 3.5. Everything else
+        in DTF requires only .NET Framework 2.0.</p>
+        
+        <p><font color="red">Note: The LINQ functionality in this DTF release is of preview quality only
+        and should not be used in production. While there are unit tests covering a wide
+        variety of queries, using advanced queries outside what is covered by the tests
+        is likely to result in unexpected exceptions, and retrieved data might possibly be
+        incorrect or incomplete. An updated LINQ to MSI library is in development.</font></p>

+                <p><b>Caveats</b></p>
+                <p>Before choosing to write a custom action in managed code instead of
+                traditional native C++ code, you should carefully consider the following:</p>
+                <ul>
+                    <li><p>Obviously, it introduces a dependency on the .NET Framework. Your
+                    MSI package should probably have a LaunchCondition to check for the presence
+                    of the correct version of the .NET Framework before anything else happens.</p></li>
+                    <li><p>If the custom action runs at uninstall time, then even the uninstall of
+                    your product may fail if the .NET Framework is not present. This means a
+                    user could run into a problem if they uninstall the .NET Framework before
+                    your product.</p></li>
+                    <li><p>A managed custom action should be configured to run against a specific
+                    version of the .NET Framework, and that version should match the version your
+                    actual product runs against. Allowing the version to "float" to the latest
+                    installed .NET Framework is likely to lead to compatibility problems with
+                    future versions. The .NET Framework provides side-by-side functionality for
+                    good reason -- use it.</p></li>
+
+                </ul>
+                <p><br/></p>
+                <p><b>How To</b></p>
+        <ul>
+        <li><p>A custom action function needs to be declared as 
+        <tt>public static</tt> (aka <tt>Public Shared</tt> in VB.NET). It takes one parameter which is 
+        a <a href="DTFAPI.chm::/html/T_Microsoft_Deployment_WindowsInstaller_Session.htm">Session</a> object, and returns a 
+        <a href="DTFAPI.chm::/html/T_Microsoft_Deployment_WindowsInstaller_ActionResult.htm">ActionResult</a> enumeration.</p>
+        <pre><font face="Consolas, Courier New">    [CustomAction]
+    <font color=blue>public</font> <font color=blue>static</font> ActionResult MyCustomAction(Session session)</font></pre><br />
+        <li><p>The function must have a 
+        <a href="DTFAPI.chm::/html/T_Microsoft_Deployment_WindowsInstaller_CustomActionAttribute.htm"
+        >CustomActionAttribute</a>, which enables it to be 
+        linked to a proxy function. The attribute can take an optional 
+        &quot;name&quot; parameter, which is the name of the entrypoint
+        that is exported from the custom action DLL.</p>
+        <li><p>Fill in MSI CustomAction table entries just like you 
+        would for a normal type 1 native-DLL CA. Managed CAs can also work just 
+        as well in deferred, rollback, and commit modes.</p>
+        <li><p>If the custom action function throws any kind of 
+        Exception that isn't handled internally, then it will be caught by the proxy 
+        function. The Exception message and stack trace will be printed to the 
+        MSI log if logging is enabled, and the CA will return a failure code.</p>
+        <li><p>To be technically correct, any MSI handles obtained should be 
+        closed before a custom action function exits -- otherwise a warning 
+        gets printed to the log. The handle classes in the managed library 
+        (<a href="DTFAPI.chm::/html/T_Microsoft_Deployment_WindowsInstaller_Database.htm">Database</a>,
+        <a href="DTFAPI.chm::/html/T_Microsoft_Deployment_WindowsInstaller_View.htm">View</a>,
+        <a href="DTFAPI.chm::/html/T_Microsoft_Deployment_WindowsInstaller_Record.htm">Record</a>,
+        <a href="DTFAPI.chm::/html/T_Microsoft_Deployment_WindowsInstaller_SummaryInfo.htm">SummaryInfo</a>)
+        all implement the IDisposable interface, 
+        which makes them easily managed with C#'s <tt>using</tt> 
+        statement. Alternatively, they can be closed in a finally block. 
+        As a general rule, <i>methods</i> return new handle objects that should be 
+        managed and closed by the user code, while <i>properties</i> only return a reference
+        to a prexisting handle object.</p></li>
+        <li><p>Don't forget to use a <a href="caconfig.htm">CustomAction.config</a> file to
+        specify what version of the .NET Framework the custom action should run against.</p></li>

+  <!-- 
+    Microsoft ResX Schema 
+    
+    Version 2.0
+    
+    The primary goals of this format is to allow a simple XML format 
+    that is mostly human readable. The generation and parsing of the 
+    various data types are done through the TypeConverter classes 
+    associated with the data types.
+    
+    Example:
+    
+    ... ado.net/XML headers & schema ...
+    <resheader name="resmimetype">text/microsoft-resx</resheader>
+    <resheader name="version">2.0</resheader>
+    <resheader name="reader">System.Resources.ResXResourceReader, System.Windows.Forms, ...</resheader>
+    <resheader name="writer">System.Resources.ResXResourceWriter, System.Windows.Forms, ...</resheader>
+    <data name="Name1"><value>this is my long string</value><comment>this is a comment</comment></data>
+    <data name="Color1" type="System.Drawing.Color, System.Drawing">Blue</data>
+    <data name="Bitmap1" mimetype="application/x-microsoft.net.object.binary.base64">
+        <value>[base64 mime encoded serialized .NET Framework object]</value>
+    </data>
+    <data name="Icon1" type="System.Drawing.Icon, System.Drawing" mimetype="application/x-microsoft.net.object.bytearray.base64">
+        <value>[base64 mime encoded string representing a byte array form of the .NET Framework object]</value>
+        <comment>This is a comment</comment>
+    </data>
+                
+    There are any number of "resheader" rows that contain simple 
+    name/value pairs.
+    
+    Each data row contains a name, and value. The row also contains a 
+    type or mimetype. Type corresponds to a .NET class that support 
+    text/value conversion through the TypeConverter architecture. 
+    Classes that don't support this are serialized and stored with the 
+    mimetype set.
+    
+    The mimetype is used for serialized objects, and tells the 
+    ResXResourceReader how to depersist the object. This is currently not 
+    extensible. For a given mimetype the value must be set accordingly:
+    
+    Note - application/x-microsoft.net.object.binary.base64 is the format 
+    that the ResXResourceWriter will generate, however the reader can 
+    read any of the formats listed below.
+    
+    mimetype: application/x-microsoft.net.object.binary.base64
+    value   : The object must be serialized with 
+            : System.Runtime.Serialization.Formatters.Binary.BinaryFormatter
+            : and then encoded with base64 encoding.
+    
+    mimetype: application/x-microsoft.net.object.soap.base64
+    value   : The object must be serialized with 
+            : System.Runtime.Serialization.Formatters.Soap.SoapFormatter
+            : and then encoded with base64 encoding.
+
+    mimetype: application/x-microsoft.net.object.bytearray.base64
+    value   : The object must be serialized into a byte array 
+            : using a System.ComponentModel.TypeConverter
+            : and then encoded with base64 encoding.

+  <!-- 
+    Microsoft ResX Schema 
+    
+    Version 1.3
+    
+    The primary goals of this format is to allow a simple XML format 
+    that is mostly human readable. The generation and parsing of the 
+    various data types are done through the TypeConverter classes 
+    associated with the data types.
+    
+    Example:
+    
+    ... ado.net/XML headers & schema ...
+    <resheader name="resmimetype">text/microsoft-resx</resheader>
+    <resheader name="version">1.3</resheader>
+    <resheader name="reader">System.Resources.ResXResourceReader, System.Windows.Forms, ...</resheader>
+    <resheader name="writer">System.Resources.ResXResourceWriter, System.Windows.Forms, ...</resheader>
+    <data name="Name1">this is my long string</data>
+    <data name="Color1" type="System.Drawing.Color, System.Drawing">Blue</data>
+    <data name="Bitmap1" mimetype="application/x-microsoft.net.object.binary.base64">
+        [base64 mime encoded serialized .NET Framework object]
+    </data>
+    <data name="Icon1" type="System.Drawing.Icon, System.Drawing" mimetype="application/x-microsoft.net.object.bytearray.base64">
+        [base64 mime encoded string representing a byte array form of the .NET Framework object]
+    </data>
+                
+    There are any number of "resheader" rows that contain simple 
+    name/value pairs.
+    
+    Each data row contains a name, and value. The row also contains a 
+    type or mimetype. Type corresponds to a .NET class that support 
+    text/value conversion through the TypeConverter architecture. 
+    Classes that don't support this are serialized and stored with the 
+    mimetype set.
+    
+    The mimetype is used forserialized objects, and tells the 
+    ResXResourceReader how to depersist the object. This is currently not 
+    extensible. For a given mimetype the value must be set accordingly:
+    
+    Note - application/x-microsoft.net.object.binary.base64 is the format 
+    that the ResXResourceWriter will generate, however the reader can 
+    read any of the formats listed below.
+    
+    mimetype: application/x-microsoft.net.object.binary.base64
+    value   : The object must be serialized with 
+            : System.Serialization.Formatters.Binary.BinaryFormatter
+            : and then encoded with base64 encoding.
+    
+    mimetype: application/x-microsoft.net.object.soap.base64
+    value   : The object must be serialized with 
+            : System.Runtime.Serialization.Formatters.Soap.SoapFormatter
+            : and then encoded with base64 encoding.
+
+    mimetype: application/x-microsoft.net.object.bytearray.base64
+    value   : The object must be serialized into a byte array 
+            : using a System.ComponentModel.TypeConverter
+            : and then encoded with base64 encoding.
