c# - Tests are no longer executed through Visual Studio 2010 after Visual Studio 11 beta was installed

Question

I have created many TestProjects with Visual-Studio-2010 Ultimate. All tests were executed successfully (they were simple unit tests). Now I installed Visual-Studio-11 beta and I realized that they are not executed through VS-2010. I also tried it through MSTest (2010) from command line without success. The test execution seems to start (and never ends) but the tests are not executed without reporting any error. Through VS-11 everything works fine.

Has anyone the same issue?

Answer 1

Have you checked this: MSTest not working after installing vs11 next to vs10

To paraphrase the official answer from Microsoft in the above link:

This is a known issue with Visual Studio 2010 which got fixed in 2010 SP1

Get SP1 from here.
