I see. I think we just need the old behavior – that is “Initialize” and “initialize” shouldn’t be mangled and so they will always be different methods not overriding each other.

Because if now one of the inheriting ruby classes defines an initialize method then it is mapped to the initialize method of the C# base class. This initialize method of my controller is totally different from the initialize method of the parent controller in C# it wouldn't be an override. Is there a way to tell IronRuby it shouldn't walk up the chain except when called super and to disregard the C# implemented method? I tried using alias_method but that didn't help. public abstract class ControllerBase { public virtual void Initialize(RequestContext context){ // do stuff here } } /* More Subclasses in C# go here none override Initialize */ class Controller < System::Web::Mvc::IronRuby::Controllers::RubyController # An attempt to put the base method out of play alias_method :base_controller_initialize, :initialize # This approach had different problems # undef_method :initialize def initialize; end end class ApplicationController < Controller def initialize(user_svc=nil) @user_service = user_svc||UserService.new(uow_scope) end end In the ApplicationController it now says that the first argument is of type RequestContext which isn't what there is supposed to be there. It should be a UserService In this case the initialize method is not that extremely important because it was there to make unit testing easier. I can set the dependencies some other way. At this point I'm more curious about how it works or will work in the future, CLR interop has been very interesting so far :) --- Met vriendelijke groeten - Best regards - Salutations Ivan Porto Carrero Blog: http://flanders.co.nz Twitter: http://twitter.com/casualjim Author of IronRuby in Action (http://manning.com/carrero) On Sun, Jul 26, 2009 at 10:34 AM, Ivan Porto Carrero <[email protected]<mailto:[email protected]>> wrote: Thanks that did it.
