[mono-android] The program 'Mono' has exited with code 255 (0xff).

[Jonathan Pobst]

Are there any error messages in logcat?

http://mono-android.net/Documentation/Guides/Android_Debug_Log

Does it crash without debugging as well?

Unfortunately, without source code or an error message, there isn't 
anything useful we can do.
