[Mono-osx] How to export an array

I don't get a crash if I change int to NSNumber in my example code, so
this makes me think that I can only export NS/Mac types. Is that right?

Ideally I would like to create an array of my own types and bind them to
a NSPopupButton with control over the displayed text. This is trivial in
.NET/WinForms. Is it possible with MonoMac somehow?

thanks, Andy
