How come Windows.Forms does not work on Win32 without Wine?  
That does not really make sense to me.  
Isn't Wine supposed to emulate Win32?
Can't the assembly detect what OS its running and the either use Wine, or
just directly use the kernel?  
Why are the DLL-names hard coded using libxxx.dll.so naming conventions
[since I get an error message that libxxx.dll.so.dll is missing]?  
Isn't that platform specific and a general issue for any share
library/PInvoke and should only use xxx, and then depending on the platform
it gets expanded to libxxx.dll.so on Unix [actually why not libxxx.so, since
java does that too], or to xxx.dll on Win32.

I guess those might be just stupid questions, but to me the design choices
are not apparent and/or transparent...
