Q:

ASP.NET MVC Area not picking up the correct route

I am in the process of debugging a routing issue on my MVC 3 application and I am using Phil Hacks routing debugger.
I cannot seem to work out where the route highlighted in yellow below is originating.  Each time I run my application with the following request
http://www.mywebsite.com/auth/login?ReturnUrl=/
this route comes first and then gives me a 404 error as I do not have an index action. As you can see I have set my default routes to use the Login action method but still this route persists.

I have the following route configurations: 
AuthAreaRegistration
public class AuthAreaRegistration : AreaRegistration
{
    public override string AreaName
    {
        get
        {
            return "Auth";
        }
    }

    public override void RegisterArea(AreaRegistrationContext context)
    {
        context.MapRoute(
            "login",
            "auth/login/{*returnPath}",
            new { controller = "Auth", action = "LogIn", id = UrlParameter.Optional }
        );

        context.MapRoute(
            "Auth_default",
            "Auth/{controller}/{action}/{id}",
            new { controller = "Auth", action = "LogIn", id = "" }
        );
    }
}

Global.asax (Using T4 MVC Templates)
    public static void RegisterRoutes(RouteCollection routes)
    {
        routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

        routes.MapRoute(
            "Home",
            "{controller}/{action}/{id}",
            MVC.Home.Index(), new { id = UrlParameter.Optional },
            new string[] { "MyNamespace.WebUI.Controllers" }

        );

        routes.MapRoute(
            "Default",
            "{controller}/{action}/{id}",
            MVC.Home.Index(), new { id = UrlParameter.Optional },
            new string[] { "MyNamespace.WebUI.Controllers" }
        );
    }

A:

I don’t like to answer my own question but after a day of trying to solve this problem I thought I would post the answer in case anyone else has the same issue.
It turns out that my application was holding onto old routes and populating them into my route collection. I deleted all the files in my bin folder and rebuilt my solution and everything worked as it should.
I have answered this question in a little more detail here: 
Does ASP.NET MVC create default routes for areas
