Today I tried to use the Definition of test sessions for the first time.
I was really happy because I have to do a lot of changes in different layers.
My Approach was to add all the unit tests that cover my current changes into one test session.
My happyness was gone after restarting VS because of too high Memory consumption and then I realized that the test session has gone.
I hope there will be a persisting mechanism in one of the upcoming release and til then I try to go ahead without using the test sessions.
They are really a great idea but are unusable without a Chance of persisting.
