Possible issue with Microsoft Fakes

[avivanoff]

A project that uses MSTest.Sdk/3.7.0 and EnableMicrosoftTestingExtensionsFakes set to true has issues execution tests that use fakes. Partial trace output:

  Message:
Test method TestMethod1 threw exception: 
Microsoft.QualityTools.Testing.Fakes.UnitTestIsolation.UnitTestIsolationException: Failed to resolve profiler path from COR_PROFILER_PATH and COR_PROFILER environment variables.

  Stack Trace: 
IntelliTraceInstrumentationProvider.ResolveProfilerPath()
IntelliTraceInstrumentationProvider.Initialize()
UnitTestIsolationRuntime.InitializeUnitTestIsolationInstrumentationProvider()
ShimRuntime.CreateContext()

Unfortunately, I was not able to create a project to reproduce the issue.

Some additional observations:

• Test project targets .NET Framework 4.8.
• Running EXE directly results in the same error.
• Running the tests using vstest.console.exe has no issues.
• Converting back to non-MSTest.Sdk works as expected.

Finally, I was able to create a sample project.
