ASP.NET MVC 2 Preview 1 - Problem compiling StructureMap Controller Factory

I have a project for which I use StructureMap for dependency injection. The project compiles fine as a MVC project but after moving everything to a MVC2 project I am now receiving the following error:

Test.Web.Controllers.StructureMapControllerFactory.GetControllerInstance(System.Type)': no suitable method found to override C:\Test\Web\Controllers\StructureMapControllerFactory.cs 11 40 Test.Web

Here is my StructureMapControllerFactory:

using System;
using System.Web.Mvc;
using StructureMap;

namespace Test.Web.Controllers
{
    public class StructureMapControllerFactory : DefaultControllerFactory
    {

        protected override IController GetControllerInstance(Type controllerType)**
        {

            IController result = null;
            try
            {
                if (controllerType == null) return base.GetControllerInstance(controllerType);
                result = ObjectFactory.GetInstance(controllerType) as Controller;

            }
            catch (StructureMapException)
            {
                System.Diagnostics.Debug.WriteLine(ObjectFactory.WhatDoIHave());
                throw;
            }

            return result;
        }

    }
}

I have found one post semi-related to this issue but it did not offer any insight as to how to resolve my issue: MVC 2 preview 1 - methods with parameters in the controller fail to load

Obviously I must be missing a change from the 1.0-2.0 progression, but I am not sure what changed. Any help is always appreciated.

Craig Stuntz is very correct here.

Just make sure you don't forget to reference System.Web.Routing in addition if your DI is in a different project than you MVC app.

For some reason there were no errors showing in the IDE for me but on compile I would still get a GetControllerInstance "no suitable method found to override."

Once I corrected the missing referenced assembly of System.Web.Routing, all was well...

I traced it with the Reflector, and indeed the function signature is changed. the

protected internal virtual IController GetControllerInstance(RequestContext requestContext, Type controllerType)

the MVC 2 dll resides here: C:\Program Files\Microsoft ASP.NET\ASP.NET MVC 2\Assemblies\System.Web.Mvc.dll

Thanks, it solved my issue!

The signature of this method changed. There is now a first argument of RequestContext:

protected override IController GetControllerInstance(
    RequestContext requestContext, 
    Type controllerType)

You'll also need to change your call to base.GetControllerInstance:

if (controllerType == null) 
    return base.GetControllerInstance(requestContext, controllerType);
