ASP.NET MVC `Html.ActionLink` between “Areas”

Question

I have added a new Area to my MVC3 project and I am trying to link from the _Layout page to the new Area. I have added an Area called \'Admin\' that has a controller \'Meets\'.<

I solved this problem by doing the following.

In my Global.asax.cs, I have

    public static void RegisterGlobalFilters(GlobalFilterCollection filters)
    {
        filters.Add(new HandleErrorAttribute());
    }

    public static void RegisterRoutes(RouteCollection routes)
    {
        routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
        routes.IgnoreRoute("{*favicon}", new { favicon = @"(.*/)?favicon.ico(/.*)?" });
    }

    protected void Application_Start()
    {
        //Initialise IoC
        IoC.Initialise();

        AreaRegistration.RegisterAllAreas();
        RegisterGlobalFilters(GlobalFilters.Filters);
        RegisterRoutes(RouteTable.Routes);
    }

In my PublicAreaRegistration.cs (Public Area), I've got

public class PublicAreaRegistration : AreaRegistration
{
    public override string AreaName
    {
        get
        {
            return "Public";
        }
    }

    public override void RegisterArea(AreaRegistrationContext context)
    {
        context.MapRoute("Root", "", new { controller = "Home", action = "Index" });

        context.MapRoute(
            "Public_default",
            "Public/{controller}/{action}/{id}",
            new { controller = "Home", action = "Index", id = UrlParameter.Optional }
            , new[] { ".Areas.Public.Controllers" }
        );
    }
}

In my AuthAreaRegistration.cs (Area for Restricted access), I've got

public class AuthAreaRegistration : AreaRegistration
{
    public override string AreaName
    {
        get
        {
            return "Auth";
        }
    }

    public override void RegisterArea(AreaRegistrationContext context)
    {
        context.MapRoute(
            "Auth_default",
            "Auth/{controller}/{action}/{id}",
            new { controller = "Home", action = "Index", id = UrlParameter.Optional }
        );
    }
}

And finally, my links in my *.cshtml pages would be like

1) @Html.ActionLink("Log Off", "LogOff", new{area= "Public", controller="Home"})

or

2) @Html.ActionLink("Admin Area", "Index", new {area= "Auth", controller="Home"})

Hope this saves someone hours of research! BTW, I'm talking about MVC3 here.

Kwex.
