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!!
Check out https://msdn.microsoft.com/en-us/vstudio/ff655021.aspx for more details. It has an excellent set of Getting Started resources for working with Feature Pack 2.
Enjoy!
