Breakpoints cause app to crash in new Android version 4.2.2

Hi,

I have just updated my HTC One X to:

Android version 4.2.2 HTC Sense version 5.0 Software Number 4.18.206.4 HTC SDK API Level 5.41

and everytime my app hits a breakpoint in either Visual Studio 2010 or Xamarin Studio, it causes an error 'System Null Exception:Loading' and then crashes the app. If i run this on an older android version it runs and breaks fine.

If I remove all break points and run on the new android version, it all works fine. its everytime I hit a break point.

Here is the few lines of code from my output when the break point is hit.

Mono.Android.VisualStudio.MonoAndroidPackage Verbose: 0 : AD7DebugExceptionEvent ctor: An unhandled exception occured. Mono.Android.VisualStudio.MonoAndroidPackage Verbose: 0 : AD7DebugExceptionEvent GetException: An unhandled exception occured. Mono.Android.VisualStudio.MonoAndroidPackage Verbose: 0 : AD7DebugExceptionEvent GetException: An unhandled exception occured. Mono.Android.VisualStudio.MonoAndroidPackage Verbose: 0 : AD7DebugExceptionEvent GetExceptionDescription: An unhandled exception occured.

Hope you guys can help.

Thanks.

Sam
