How do I use Session_Start in ASP.NET MVC?

void Session_Start(object sender, EventArgs e) {

            if (HttpContext.Current.Session == null)
            {
                Debug.WriteLine("null session");
            }
            else
            {
                Debug.WriteLine("There is a session");
                HttpContext.Current.Session["Foo"] = 100;
                HttpContext.Current.Session["Bar"] = "Abc";
            }

 }

<system.web>
  <sessionState cookieName="auth" mode="InProc" timeout="480"/>
</system.web>
