User Authentication

Question

Hi

  If user is not authenticated Login Page should Open but it is not opening. I need if User is not Login then Login View should be displayed.How this can be done

Home Controller

    public class HomeController : Controller
    {
        [AllowAnonymous]
        public ActionResult Index()
        {
            return View();
        }
        public ActionResult Login()
        {
            return PartialView("_Login");
        }

        [HttpPost]
        [Authorize]
        public ActionResult Logout()
        {
            FormsAuthentication.SignOut();
            return RedirectToAction("Index");
        }

}

Home Index - Blank Page

Route.Config

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

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

Web.Config

    <authentication mode="Forms">
      <forms loginUrl="~/Home/Login" timeout="2880" />
    </authentication>

Thanks
