ASP.Net身份授权不起作用

Question

我正在编写一个使用Asp.net MVC 5和身份的小应用程序。我遇到的问题是authorize属性不起作用，即指定的角色不被视为授权角色。我已经尝试过其他帖子中有类似问题的建议但没有运气。欢迎任何帮助。

使用授权的控制器方法：

    // GET: /ToDo/All
    [Authorize(Roles="Boss")]
    public async Task<ActionResult> All()
    {
        return View(await db.ToDoes.ToListAsync());
    }

带有dbcontext的AppModel.cs

       using System;
       using System.Collections.Generic;
         using System.Data.Entity;
using System.Linq;
using System.Web;
using Microsoft.AspNet.Identity.EntityFramework;
using System.ComponentModel.DataAnnotations;

namespace AspIdentityTrial.Models
{
    public class ApplicationUser : IdentityUser
    {
        public string HomeTown { get; set; }
        public virtual ICollection<ToDo> ToDoes { get; set; }

        public virtual MyUserInfo MyUserInfo { get; set; }
    }

    public class MyUserInfo
    {
        public int Id { get; set; }
        public string FirstName { get; set; }
        public string LastName { get; set; }
    }

    public class ToDo
    {
        public int Id { get; set; }
        public string Description { get; set; }
        public bool IsDone { get; set; }
        public virtual ApplicationUser User { get; set; }
    }

    public class TrialDbContext : IdentityDbContext<ApplicationUser>
    {
        public TrialDbContext()
            : base("DefaultConnection")
        {
            this.Configuration.LazyLoadingEnabled = true;
        }

        protected override void OnModelCreating(DbModelBuilder modelBuilder)
        {
            base.OnModelCreating(modelBuilder);

            // Change the name of the table to be Users instead of AspNetUsers
            modelBuilder.Entity<IdentityUser>()
                .ToTable("Users");
            modelBuilder.Entity<ApplicationUser>()
                .ToTable("Users");
        }


        public DbSet<ToDo> ToDoes { get; set; }

        public DbSet<MyUserInfo> MyUserInfo { get; set; }
    }


}
