It looks like the project is using some Winforms 2.0 functionality,  
but I think only Winforms 1.1 is currently supported in Mono.

I was able to get it to build under Mono (but only after a fashion,  
after some tweaking) but there are a few elements of the application I  
had to modify.

e.g. System.Configuration.ApplicationSettingsBase,  
Application.SetCompatibleTextRenderingDefault and  
System.Windows.Forms.AutoScaleMode are not supported in Mono 1.9.1, it  

FWIW, I've had no problems at all building under Mono on Mac OS (e.g.  
with Mono Develop) then running those binaries under .NET on Windows,  
but then I'm not coming from a .NET developer background so I haven't  
had to worry about .NET functionality might not be in Mono, and so  
I've found it very straightforward working that way round.
