My application for windows phone uses Microsoft Ad SDK and recently I have noticed a lot of crashes in the application which I feel has something to do with the Ad SDK/control. The stack trace provided by the App Hub for the app can be accessed from here.
Any idea what is causing the crash?
By the stack trace I think you have the same problem that this guy had:
