I'm not sure what you are doing wrong, possibly mono isn't installed
correctly or you have mixed old and new versions in your mono install. I
just tried a fresh installation of Ubuntu Jaunty Jackalope which has mono
2.0. The SWIG C# test-suite passes. Below is a classic example build and
run. Try replicate it.

Creating some objects:
    Created circle Circle
    Created square Square

A total of 2 shapes were created

Here is their current position:
    Circle = (20 30)
    Square = (-10 5)

Here are some properties of the shapes:
   Circle
        area      = 314.159265358979
        perimeter = 62.8318530717959
   Square
        area      = 100
        perimeter = 40

Guess I'll clean up now
0 shapes remain
Goodbye
