Why doesn't IronRuby have the same tools that IronPython does?
Shortly the same support for IronRuby is arriving to visual studio. It will take maybe another couple of months but then it will get there. They first needed to get the language implementation right.
I've been using Ruby as my main scripting language for years but switched to .NET several years ago.  I'd like to continue using Ruby (primarily for testing) BUT the toolset for IronRuby is really nonexistent.  Why?
In Python, meanwhile, there are project templates and full intellisense support.  Why isn't there something like that for IronRuby?  The only thing I've been able to find on it is "there are no plans for VS integration at this time."  Why???
