PlatformNotSupportedException when running unit tests from VS

[mrek-msft]

Description

I am new in .NET runtime repo. I try run library tests in VS, but in case of some libraries (for example, System.IO.Ports, Microsoft.Extensions.Logging) some tests fails with PlatformNotSupportedException because test executable run with component implemented by .notsupported.cs platform variant (in case of Logging) and .Unix.cs variant in case of Ports. It happens only with net11 targets and do not happen with net481. It also do not happen when running dotnet build /t:Test in command line.

Did I anything wrong?

Reproduction Steps

1. Clone fresh runtime repo
2. .\build.cmd -rc Release
3. .\Build.cmd -vs Microsoft.Extensions.Logging
4. Test Explorer > Run All Tests in View

Expected behavior

Exclude tests for unsupported platform

Actual behavior

They are included multiple times. For one platform they pass, other fails.
