Can you please help me understand why this Xamarin.Mac application is crashing? I am trying to use the GUI library Xwt in Xamarin Studio on a Mac, but even the test project XamMacTest which comes with Xwt crashes. I determined that the crash happens during the call to NSApplication.Init(). I noticed that Xwt is not a Xamarin.Mac project, but instead includes a copy of Xamarin.Mac.dll. Is it possible that there is a problem with this dll file? It came with the Xwt download so I would expect it to work. If the problem is with the dll, is there a way I can change the project in Xamarin Studio so that it runs as a Xamarin.Mac project?
Here is an excerpt of what appears to be the relevant information from the crash log:
