How do I redirect to a .aspx from a Controller MVC.NET

I have a Login.aspx file in my folder Shared. When I click my logut button, it takes me to SessionController->LogOut action. I have to problems.

  1. My FormsAuthentication is not beign signed out.

  2. Gets an error when redirecting to Login.aspx:

System.InvalidOperationException: The view at '~/Views/Shared/Login.aspx' must derive from ViewPage, ViewPage, ViewUserControl, or ViewUserControl.

I got this code:

My Controller:

public class SessionController : Controller
{
    public ActionResult LogOut()
    {
        if (Request.Cookies["Usuario"] != null)
        {
            FormsAuthentication.SignOut();
            var c = new HttpCookie("Usuario");
            c.Expires = DateTime.Now.AddDays(-1);
            Response.Cookies.Add(c);
        }
        return View("Login");
    }
}

My calling from HTML to de Conttroller:

<ul class="dropdown-menu">
    <li><a id="logout" href="~/Session/LogOut">Log out</a></li>
</ul>

And Login.aspx:

<%@ Page Language="C#" %>

<%@ Import Namespace="System.Data" %>
<%@ Import Namespace="System.Data.SqlClient" %>
<%@ Import Namespace="System.Web.Security " %>
<%@ Import Namespace="System.IO" %>

Hope this helps

return Redirect("url");

or

return RedirectToRoute("routename"); // Specify route in the Route Config file.

As the exception says, MVC views have to inherit specific MVC infrastructure classes in order to be recognized as MVC views.

In case of the ASPX view engine you need to specify this in an explicit way, for example

<%@ Page Language="C#" 
    Inherits="System.Web.Mvc.ViewPage<YourModelClassName>" %>

or

    Inherits="System.Web.Mvc.ViewPage"

if your view doesn't expect any model.
