ASP.net MVC with IronRuby?

Question

Does asp.net mvc development necessarily means c# should be in it? Is it painful to use IronRuby(is it possible?) and how ironruby differs from ruby?

Answer 1

ASP.Net supports any CLR-languages for the server side (C# and VB.NET). Using DLR languages will require a bit of tweaking as posted by Phil Haak here, and code updated by Ivan Porto Carrero and available here.

Differences between IronRuby and Ruby are mainly not yet supported features, and I don't know if there is a complete list somewhere but you can have a summary here.
