Steps to reproduce

We’ll need a project with subprojects referenced in .csproj with $(MSBuildStartupDirectory). The project above demonstrates this scenario: https://github.com/pfrozi/project-levels-test

Debug any test via code lens (clicking on “debug test” above the method on UnitTest.cs).

Expected behavior

Debugger goes into the first breakpoint of a test method.

Actual behavior

Failed to start debugger: "System.NullReferenceException: Object reference not set to an instance of an object

@pfrozi I used the git submodule update and cloned the two submodules. But I am certain now that there is a problem with the references here. The tests use the project-level1 project but the reference to them is not present in the csproj. I resolved all the necessary references with absolute paths and everything is working fine for me now. Could you try that ?
