I’ve successfully(\*) built using “rake compile” and the Visual C# 2008  
Compiler version 3.5.21022.8.

I think you’ll have to post a bit more about the exact error you are  
getting.

- I’ll caveat that with the fact I am running into a problem building  
the IronRubyTestHost (the path to System.Windows.Forms.dll is wacked).  
But rbx, tests, etc. all work.

We’re all using the 3.5.21022.8 compiler here (but aren’t using any of  
the C# 3.0 features in the codebase to maintain compat with the C# 2.0  
compiler).
