I am seeing the same thing.  Even pages without Telerik controls are causing Visual Studio to crash.  The only thing that makes it not crash is removing the Telerik controls from the References.  What is really strange is if I load the MetroPageTransitions project that you guys posted it works just fine.  So why does my project crash?

UPDATE: ** Never mind, solved my problem.
