Sure, but that's not how you call an arbitrary native method. It's  
just a call to a wrapper method. Of course, I guess you have wrapped  
all or most of Cocoa...

Sorry, I wasn't very clear. What I meant was that instead of the  
programmer claiming ownership of an object via a retain call the .NET  
runtime itself claims ownership which it releases via Dispose or the  
Objc3.NSObject finalizer. I'd like to experiment with using the native  
GC though, it seems like it would be doable...
