[Ironruby-core] Can't create instances

Does any of the C# subclasses have Initialize method? That might be the problem. I’ll fix it asap.

It's a subclass of RubyController (http://github.com/casualjim/ironrubymvc/blob/f9b28881187865dcff3389231e627ee2c4f93d14/IronRubyMvc/Controllers/RubyController.cs)

There are no constructors defined in any of the class definitions.

HomeController.rb:

Hi



I just updated from github and ironrubymvc broke.



This method would happily execute before the update.



public object CreateInstance(RubyClass rubyClass)

        {

            return Operations.CreateInstance(rubyClass);

        }



Now it throws an exception. Do I need to change something?
