IronRuby offers some cool Ruby scripting functionality for .NET. The wiki offers setup instructions for Visual Studio 2005, but these instructions won’t work with Visual Studio 2008, at least under Vista for 64-bit machines.  In particular, the location of resgen.exe provided by the wiki is incorrect.  The actual location is:

 C:\Program Files\Microsoft SDKs\Windows\v6.0A\Bin  

 Let the good times roll!
