After installing the Release Candidate bits in our development environment, I found out a very great improvement. The output information from MSTest, used when running unit tests, is finally nicely integrated in the build report. Before you only got an error like this when running the tests failed
MSTest.exe returned an exit code of 1 indicating that not all tests passed.
Now you get a full report containing all the tests and their results, any errors and every other information you could ever need. Great!
