Blank screen when exception thrown, no error message

I’m trying to upgrade a Windows Phone project to from Monogame 3.2 to 3.3 and switch to the MGCB (original version uses XNA to build the content XNBs), and I’m seeing strange behaviour when trying to debug - when an error occurs, the device screen goes blank and the framerate drops to zero (so I’m assuming the game freezes), but I get no exception in Visual Studio - no error message, no highlight of where in the code the exception occured, no information as to the cause of the error.

Has anyone else seen this behaviour, and if so, how do I work round it?



have you tried enabling all exceptions?

Debug menu -> Exceptions, enable all CLR exceptions.

In WP8 for some reason exceptions which happen in a thread seem to fail silently
