title: Migrating global.asax to ASP.NET 5
body: <p>Few days ago .NET Core RC1 got released and I gave it a go for the first time after reading a lot about it, I like it but its a bit different. I am trying to migrate a small blog (built in MVC5) to MVC 6 &amp; .NET Core. It wasn't hard but I am really struggling to recreate the exact same global.asax settings I had in MVC 5, ASP.NET 5 no longer has global.asax so I am unable to figure out what the replacement for most of the settings are?</p>
  
  <pre><code>    protected void Application_Start()
      {
          ViewEngines.Engines.Clear();
          ViewEngines.Engines.Add(new RazorViewEngine());
  
          MvcHandler.DisableMvcResponseHeader = true;
          AntiForgeryConfig.SuppressXFrameOptionsHeader = true;
  
          BundleConfig.RegisterBundles(BundleTable.Bundles);
          RouteConfig.RegisterRoutes(RouteTable.Routes);
      }
  
      protected void Application_BeginRequest()
      {
          Response.AddHeader("X-Frame-Options", "DENY");
      }
  
      protected void Application_EndRequest()
      {
          if (Response.StatusCode != 301 &amp;&amp; Response.StatusCode != 302) return;
  
          var targetUrl = Response.RedirectLocation.Replace("ReturnUrl", "url");
          Response.RedirectLocation = targetUrl;
      }
  
      protected void Application_AuthenticateRequest(object sender, EventArgs e)
      {
          string typeName;
  
          byte userType = (byte)(Context.Request.IsAuthenticated ? byte.Parse(User.Identity.Name.Split('|')[2]) : 1);
  
          switch (userType)
          {
              case 1: { typeName = "Client"; break; }
              case 2: { typeName = "Admin"; break; }
              default: { typeName = "Client"; break; }
          }
  
          var roles = new[] { typeName };
  
          if (Context.User != null)
          {
              Context.User = new GenericPrincipal(Context.User.Identity, roles);
          }
      }
  
      private void Application_Error(object sender, EventArgs e)
      {
          Exception ex = Server.GetLastError();
  
          if (ex is HttpAntiForgeryException)
          {
              Response.Clear();
              Server.ClearError();
              Response.Redirect("/error/cookie", true);
          }
      }
  </code></pre>
  
  <p>PLEASE, is there a way to get the above code to work in MVC 6 without leaving any of the settings? This is a deal breaker for me, THANK YOU.</p>
