As I understood the answer, you need to catch and rethrow unhandled exception, right? You can add handler for the AppDomain.UnhandledException Event:

  AppDomain currentDomain = AppDomain.CurrentDomain;
  currentDomain.UnhandledException += new UnhandledExceptionEventHandler(MyHandler);

  static void MyHandler(object sender, UnhandledExceptionEventArgs args)
  {
        Exception e = (Exception) args.ExceptionObject;
        // handle exception here, you can easily package exceptions there.
  }

Update:

I've discovered another event in AppDomain class, AppDomain.FirstChanceException Event:

Occurs when an exception is thrown in managed code, before the runtime searches the call stack for an exception handler in the application domain.

May be this can solve your problem - this event occurs before any code in catch blocks.
