Found out this is a problem because FCS outputs this folder that doesn't exist. The reason it's outputting this folder is our design time build is running at the same time as our test discovery and it's colliding giving strange results.

I'm going to put some guards in the file watching for ProjectSnapshots but I think the ultimate fix is to have our test discovery run with different BaseIntermediateOutputPath and BaseOutputPath.

I think the ultimate fix is to have our test discovery run with different BaseIntermediateOutputPath and BaseOutputPath.

Yes, this is perfectly fine. We may also want test discovery and any other per-project operations to use BuildProjectReferences=false to skip building referenced projects to prevent unnecessary re-builds.
