No idea, I don't use Dumbarton in my Cocoa app. But even when using
Dumbarton you can use the embedding functions of Mono directly like
Dumbarton as a wrapper does internally, or if it's missing in
Dumbarton patch it in.
The initWithMonoObject:NULL above will not lead to success as Mono
cannot retrieve a MonoClass* from a NULL reference. Logically I would
expect such ObjC messages at a class wrapper, say result = [myClass
