A compiler test is failing here while this doesn't touch the compiler layer at all.

Closing and re-opening for a new build.

I very much appreciate you doing this. I've seen those projects being built in unrelated test runs.

@sharwell Is there a way to limit local build/tests to only net5.0? Currently everything seems to run twice.
