When compiling this code:

public class WindsorControllerFactory : IControllerFactory
{
    private readonly WindsorContainer _container;

    public WindsorControllerFactory(WindsorContainer container)
    {
        _container = container;
    }

    public IController CreateController(RequestContext requestContext,
                                        string controllerName)
    {
        return (IController)_container.Resolve(controllerName);
    }

    public void ReleaseController(IController controller)
    {
        _container.Release(controller);
    }
}

I am getting this error:

'WindsorControllerFactory' does not implement interface member 'System.Web.Mvc.IControllerFactory.CreateController(System.Web.Routing.RequestContext, string)'

Well, it obviously implements this member. Has anyone encountered this problem?
