It seems that there is a problem with package "MSTest.TestFramework": "1.0.5-preview". I downgraded it to "MSTest.TestFramework": "1.0.4-preview" and tests are running fine now.

For me it's working also with "1.0.4-preview".

Also seeing the same issue - error with 1.0.5 but not 1.0.4.

Also seeing the same issue with "1.0.6-preview".
This can be fixed by upgrading dotnet-test-mstest to "1.1.2-preview".

Try to add reference to MSTest.TestAdapter
