Description Jerome Laban 2017-04-04 14:23:17 UTC
When building a Xamarin.Android project referenced by another project, the generated MDB files get deleted by the IncrementalClean target, making a build fail when run in parallel.

The target _RegisterMdbFilesWithFileWrites incorrectly registers mdb files for the IncrementalClean target, which get deleted.

The target should look for *.mdb files, not *.dll.mdb files, as follows: 

	<Target Name="_RegisterMdbFilesWithFileWrites" BeforeTargets="IncrementalClean">  
		<CreateItem Include="$(OutDir)*.mdb;$(MonoAndroidIntermediateAssemblyDir)*.mdb">  
			<Output TaskParameter="Include" ItemName="_FilesToRegister" />  
		<CreateItem Include="$([System.IO.Path]::GetFullPath('%(_FilesToRegister.Identity)'))"
			<Output TaskParameter="Include" ItemName="_CleanCurrentFileWrites" />

I believe I am running into a similar issue, but on a much larger scale, that is not letting me build or debug on visual studio. Please look at bug# 54467 for details!
