[Mono-osx] Dumbarton and C# subclasses

[Hawston LLH]

I was trying the Form in the DBCocoaExample sample in Dumbarton, and
get the following errors, what I did is simply making
CurrencyConverter class inherites after Form: "public class
CurrencyConverter : System.Windows.Forms.Form".

What caught my eye is "Uncaught exception: <An exception was thrown by
the type initializer for System.Windows.Forms.XplatUI", is XplatUI
refer to X11? is there something wrong with this? In Terminal, i can
build an exe and run it without error. Please help.
