mono - the requested feature is not implemented - what feature?

Question

I'm receiving this error when I start my application but I have NO idea what feature isn't implemented. It doesn't print anything to the console or tell me what isn't implemented.

Is there a way to figure this out? The only thing I have to go on is this error message that appears in a window:

Interestingly enough my application does start after I click ok, but I'd like to figure out what the problem is.

Answer 1

Minimize to systray is my first guess. That wasn't implemented last time I looked.

But you might be able to find a stack trace in Windows' Event Viewer -- Application Log
