My problem was roughly the following: I had an item group containing all the projects I wanted to build (some wix, some C#). Each item in that group had some metadata associated with it (things like the platform and configuration). When I invoked the msbuild task ( http://msdn.microsoft.com/en-us/library/z7f65y0d.aspx), I was passing that metadata into the Properties property. The call looked roughly like this:
<MSBuild Projects="@(MyItemGroup)" BuildInParallel="True" Properties="Configuration=%(Configuration);Platform=%(Platform)" /> When you pull out item metadata to pass in as Properties, msbuild.exe effectively invokes the MSBuild task once for every unique configuration of properties. All of my C# projects had the exact same set of metadata, so their Properties strings matched and they were all built in parallel. Each one of my wix projects had a slightly different set of metadata (not the config and platform specifically, but other things I was setting) so each one of those projects ended up being put in its own bucket and built separately. This ended up having nothing at all to do with Wix, and everything to do with my own parallel build infrastructure and the way I was invoking the MSBuild task.
