Question

Is there a way in Windows Mobile to catch global unhandled exceptions? If not, are there any workarounds? Specifically, we have a thin client app and we want to globally catch exceptions generated when the network is unavailable (so we can present a friendly message and prompt the user to try again).

This catch statement doesn’t fire when I throw an exception on button press

 try
 {
   Application.Run(new Login());
 }
 catch (Exception ex)
 {
   Debug.WriteLine("Caught " + ex);
 }

You can use an AppDomain.UnhandledException handler, but you cannot recover from it – you can only log it and shutdown the app. There’s no way to have a global handler that is recoverable (at least in the CF) because there’s no way to guarantee app state at that point.
