Visual Studio 2010 Feature Pack 2 is now available for MSDN subscribers
It’s here! There are updates to both the testing features and the code visualization & modeling features. I’m really excited about the new testing features: You’ll be able to create coded UI tests for Silverlight 4 applications!!
