Asp.net mvc 4 MVC中的默认路径问题

我无法在MVC中设置默认页面。我使用git hub的小写虚线路由作为url。当我打开我的项目，我得到404错误。当我打开localhost/home/index这样的页面时，它工作正常

using LowercaseDashedRouting;


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

        //routes.MapRoute(
        //   name: "Default",
        //   url: "{controller}/{action}/{id}",
        //   defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
        //   );
        routes.Add(new LowercaseDashedRoute("{controller}/{action}/{id}",
        new RouteValueDictionary(
        new { controller = "home", action = "Index", id = UrlParameter.Optional }),
        new DashedRouteHandler()  ) );    }}}
