FCC Coverage doesn't include Project being tested

[hughball77]

Hello!

I'm using VS Pro, trying to get some visual code coverage going and FCC seems to be what I'm looking for. I've got the latest extension installed (1.1.141) and it appears to be working, but the project I'm actually testing isn't appearing in the Coverage tab of the FCC, and therefore I don't get the actual sidebar code coverage highlighting that I'm looking for.

For example, I have two projects in my solution: Main and Main.Tests. Under Coverage, only Main.Tests shows up with the list of tests run.

Edit - I should note that my Main project is a .NET Framework 4.0 project, and my Main.Tests is a .NET 5.0 project.

Any suggestions of where I might start looking?

Thanks!

What does the FCC output window pane show ?

It's got a bunch of these:

Fine Code Coverage : ================================== START ==================================

Fine Code Coverage : Run Coverage Tool (Main.Test)

BadImageFormatException during MetadataReaderProvider.FromPortablePdbStream in InstrumentationHelper.PortablePdbHasLocalSource, unable to check if module has got local source.
Unable to instrument module: D:\----redacted----\Release\net5.0-windows\fine-code-coverage\build-output\----redacted---- because : AssemblyResolutionException for 'System.Diagnostics.EventLog, Version=0.0.0.0, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51'. Try to add <PreserveCompilationContext>true</PreserveCompilationContext> to test projects </PropertyGroup> or pass '/p:CopyLocalLockFileAssemblies=true' option to the 'dotnet test' command-line

But there's no reference to Main - it's almost like it's excluding it or it doesn't know it's there.

^^ This might be my problem - I didn't realize that unable to instrument module was coming from my Main project. I'll sort that out and report back.

I figured it out - it was two things:

• following the unable to instrument module error, I added the System.Diagnostics.ErrorLog package to my dependencies
• I had installed the FCC extension from the web, not directly from VS, which got me version 1.3.0 of coverlet.collector. Looking at my updates, 3.0.3 was available and I've now installed that

I've got code coverage highlighting where I was expecting it - thanks for being my sounding board and letting me think out loud!
