I'm working with Visual Studio Team Services for the first time, and am setting up a simple scenario of a C# class library with a MSTest project. I want to setup automated builds, which also executes the tests. However this is not working. I've searched about it a lot, and most issues seems to be related to different test adapters like NUnit. This is not the case here, since I'm just using the default testing framework.

Can anyone help me and let me know what step I'm missing or doing wrong?

The only message is "Warning: No test is available in ..." with a lot of referenced dll's.
