+In order to properly test wix.targets,
+all of the supported architectures for WixToolset.BuildTasks need to be available in the layout used in the Nuget package.
+Making this happen on every build for the solution takes too long,
+so this project relies on manually running appveyor.cmd to publish everything before the tests can be run.
+appveyor.cmd needs to be ran again every time changes are made in other projects, including the targets themselves.
