Hi @MarcoRossignoli ,

so the issue is that after changing the sourceRootMappingFilePath, the InstrumenterHelper throws an exception when trying
to load the type of the tracker.

tracker = asm.GetTypes().Single(n => n.FullName.Contains("Coverlet.Core.Instrumentation.Tracker"));

The reason is that the tracker isn't injected (or not correct) into the assembly (coverlet.core.tests). It can't be found
with the code snipped above and thus Single(n => ...) throws an exception.

It's super weird that if changing the sourceRootMappingFilePath back to the way it was before, the tracker is injected in the
assembly again. I also can't reproduce this locally and it only happens on the build server.

Any idea what could cause the tracker to not beeing injected into the assembly?

[MarcoRossignoli]

But if we disable the coverage for our tests(we don't dogfood) does it work?

[daveMueller]

Not I tried this and it didn't help. Basically every unit test that is using TestInstrumentationHelper.Run<AwaitUsing> fails. If I remove all those tests (most of them are in coverlet.core.tests\Coverage) I can get build and the remaining test green.

[daveMueller]

The issue is that Coverlet.Core.Instrumentation.Tracker isn't injected into the assembly anymore and up to now I couldn't figure out why.
