Html.ActionLink, Url.ActionLink and Html.RouteLink return empty urls

Question

Html.ActionLink, Url.ActionLink and Html.RouteLink return empty urls, even though the target url is valid and displayed properly from url?

I played around with the route but, it keeps return empty url without any exception.

You need to give us more information if we're going to help you. Your Routes, the link you're making with `RouteLink`, and your controller/actions you're trying to call with it. — George Stocker, Mar 15 '11 at 17:33

I have the same problem when upgrading my project from mvc2 to mvc3. The problem was in old global.asax file, that I put into new project.

So when I replaced old .asax onto new, actionLinks start to work properly.

Global.asax for mvc3

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using System.Web.Routing;

namespace RealtyMVC
{
public class MvcApplication : System.Web.HttpApplication
{
    //!!!add this method
    public static void RegisterGlobalFilters(GlobalFilterCollection filters)
    {
        filters.Add(new HandleErrorAttribute());
    }

    public static void RegisterRoutes(RouteCollection routes)
    {
        routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

        routes.MapRoute(
            "Default", // Route name
            "{controller}/{action}/{id}", // URL with parameters
            new { controller = "Home", action = "Index", id = UrlParameter.Optional } // Parameter defaults
        );

    }

    protected void Application_Start()
    {
        AreaRegistration.RegisterAllAreas();
        //!!!and add this call
        RegisterGlobalFilters(GlobalFilters.Filters);

        RegisterRoutes(RouteTable.Routes);
    }
}
}
