My google-fu is failing me on this one.
As a possible solution to http://stackoverflow.com/questions/1679404/unit-testing-net-3-5-projects-using-mstest-in-vs2010 (but I've put this in a seperate question because it's kind of unrelated):
Is there any information available regarding if/when .NET 4.0 support will be added to Windows Azure?
Cheers!
