Question

I am not sure what do I am missing but I really cannot refer to
User.Identity under OnActionExecuting(ActionExecutingContext filterContext)

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using System.Web.Security;
using System.Web.Routing;

.....

    public class RealUserAttribute : ActionFilterAttribute
    {
            public override void OnActionExecuting(ActionExecutingContext filterContext)
            {
                 /// if (User.Identity.IsAuthenticated)

Any clue how to fix it?

Answer 1

I found the solution.

It should be

filterContext.HttpContext.User.Identity.IsAuthenticated
