Aaron Jensen has posted the ASP.NET MVC source code on GitHub at http://github.com/machine/msmvc, inviting developers to fork the project, implement their ideas or suggestions as failing tests, and then propose these changes to the ASP.NET MVC leaders, including @haacked. Additionally, @jschementi has contributed IronRubyMvc, an extension to ASP.NET MVC that supports IronRuby, allowing developers to write controllers and other parts of their site in Ruby. This initiative, shared by Chris Wanstrath, encourages collaboration and innovation within the MVC developer community.
