        Improves the performance of managed applications by creating native images.
        Requires the .NET Framework 2.0 or newer to be installed on the target machine since
        it runs [NGen](https://learn.microsoft.com/en-us/dotnet/framework/tools/ngen-exe-native-image-generator).

        <xse:remarks>
          Native images are files containing compiled processor-specific machine code, which
          are installed into the native image cache on the local computer. The runtime
          can use native images from the cache instead using the just-in-time (JIT)
          compiler to compile the original assembly.

          The native image custom actions are configured to ignore failures so that failing
          to generate or remove a native image will not cause setup to fail and roll back.

            The directory to use for locating dependent assemblies.
            For DLL assemblies and assemblies installed to the Global Assembly Cache (GAC),
            this attribute should be set to the directory of the application which loads this
            assembly.  For EXE assemblies, this attribute does not need to be set because NGen
            will use the directory of the assembly file by default.

            The value can be in the form of a directory identifier, or a formatted string
            that resolves to either a directory identifier or a full path to a directory.

          <xs:documentation>
            The application which will load this assembly.
            For DLL assemblies which are loaded via reflection, this attribute should
            be set to indicate the application which will load this assembly.
            The configuration of the application (usually specified via an exe.config file) will be used
            to determine how to resolve dependencies for this assembly.

            The value can be in the form of a file identifier, or a formatted string
            that resolves to either a file identifier or a full path to a file.

            When a shared component is loaded at run time, using the Load method, the
            application's configuration file determines the dependencies that are loaded
            for the shared component — for example, the version of a dependency that is loaded.
            This attribute gives guidance on which dependencies would be loaded at run time in order
            to figure out which dependency assemblies will also need to have native images generated
            (assuming the Dependency attribute is not set to "no").

            This attribute cannot be set if the AssemblyApplication attribute is set on the parent
            File element (please note that these attributes both refer to the same application
            assembly but do very different things: specifiying File/@AssemblyApplication will force
            an assembly to install to a private location next to the indicated application, whereas
            this AssemblyApplication attribute will be used to help resolve dependent assemblies
            while generating native images for this assembly).
