NotImplementedException when handling errors in Global.asax Application_Error - asp.net-mvc-3

Question

I have code
protected void Application_Error(object sender, EventArgs e)
{
HttpContext ctx = HttpContext.Current;
Exception ex = ctx.Server.GetLastError();
ctx.Response.Clear();
var viewResult = new ViewResult();
if (ex.GetType() != typeof(SecurityException))
{
RequestContext rc = ((MvcHandler)ctx.CurrentHandler).RequestContext;
IController controller = new ModuleController();
var context = new ControllerContext(rc, (ControllerBase)controller);
var httpException = ex as HttpException;
if (httpException != null)
{
switch (httpException.GetHttpCode())
{
case 404:
viewResult.ViewName = "Error404";
Response.StatusCode = 404;
break;
case 500:
viewResult.ViewName = "Error500";
Response.StatusCode = 500;
break;
default:
viewResult.ViewName = "Error";
Response.StatusCode = httpException.GetHttpCode();
break;
}
}
else
{
viewResult.ViewName = "Error";
}
viewResult.ViewData.Model = new HandleErrorInfo(ex, context.RouteData.GetRequiredString("controller"), context.RouteData.GetRequiredString("action"));
viewResult.ExecuteResult(context);
ctx.Server.ClearError();
}
else
{
var context = new ControllerContext { RouteData = new RouteData() };
context.RouteData.Values.Add("controller", "Security");
context.Controller = new SecurityController();
HttpCookie cookie = this.mebershipService.GetCookie();
cookie.Expires = DateTime.Now.AddDays(-1);
this.Context.Response.Cookies.Add(cookie);
viewResult.ViewName = "HackedDetect";
Response.StatusCode = 403;
viewResult.ExecuteResult(context);
ctx.Server.ClearError();
}
}
When processing SecurityException, and the call controller that does not relate to the system (in order not to walk in a circle) on the code viewResult.ExecuteResult (context); be a NotImplementedException
But I was not clear which method or operation is not defined.
That's what copied to the clipboard from the mistakes
System.NotImplementedException not handled by user code
HResult = -2147467263
Message = The method or operation is not implemented.
Source = System.Web
StackTrace:

InnerException:
UPDATE
I'll write what I do to get this error
I created custom Identity class and when is initialized, I'm validate the cookie. If cookie not validate I create SecurityException
