Only TestM2 is run

I'm seeing a similar issue in a ASP.NET 6 project, some of my tests decorated with [DataRow] or [DynamicData] are shown in the Test Explorer but skipped when I run tests with MSTest 3.8.0, while MSTest 3.7.3 runs all of them correctly.

I don't see related error messages or any other clue in test logs 😢

@LucaBlackDragon Thanks for reporting this. This issue is specific to a new feature in 3.8.0 which is not supported for MSTest.Engine/MSTest.SourceGeneration only. So, your issue is likely to be different. Can you please open a separate issue with more details on how your test look like, etc, and if you can provide us with a repro?

Re-categorizing as feature request as the engine is totally different.
