IdentityUserLogon没有定义键

Question

让我让你明白，在我决定发布这个问题之前，我已经搜索了很多stackoverflow线程并实现了几乎所有规定的解决方案都无济于事。我试图了解如何将身份系统中的用户与项目中的其他实体相关联，因此我按照我发现的here教程进行了操作。 当我到脚手架创建一个使用ToDo.cs模型和ToDoContext.cs的ToDo控制器的时候，我总是遇到障碍，无论我做了什么，我都无法用脚手架。以下是我目前的

public class ToDo
    {

        public int Id { get; set; }

        public string Description { get; set; }

        public bool IsDone { get; set; }

        public virtual MyUser User { get; set; }


    }

public class MyUser : IdentityUser
    {
        public string HomeTown { get; set; }

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

public class ToDoContext : IdentityDbContext<MyUser>
    {
        public ToDoContext()
            :base("DefaultConnection")
        {
        }

        protected override void OnModelCreating(DbModelBuilder modelBuilder)
        {
            modelBuilder.Entity<IdentityUserLogin>().HasKey<string>(l => l.UserId);
            modelBuilder.Entity<IdentityRole>().HasKey<string>(r => r.Id);
            modelBuilder.Entity<IdentityUserRole>().HasKey(r => new { r.RoleId, r.UserId });

            base.OnModelCreating(modelBuilder);

        }

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

我在Global.asax中

Global.asax
public class MvcApplication : System.Web.HttpApplication
    {
        protected void Application_Start()
        {
            AreaRegistration.RegisterAllAreas();
            FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
            RouteConfig.RegisterRoutes(RouteTable.Routes);
            BundleConfig.RegisterBundles(BundleTable.Bundles);

            Database.SetInitializer<ToDoContext>(new ToDoInitializer());
        }
    }

public class ToDoInitializer : DropCreateDatabaseAlways<ToDoContext>
    {
        protected override void Seed(ToDoContext context)
        {
            var UserManager = new UserManager<MyUser>
            (
                new UserStore<MyUser>(context)
            );

            var RoleManager = new RoleManager<IdentityRole>

              (
                 new RoleStore<IdentityRole>(context)
              );


            string name = "Admin";
            string password = "123456";

            //Create Role Admin if it does not exist

            if (!RoleManager.RoleExists(name))
            {
                var roleresult = RoleManager.Create(new IdentityRole(name));
            }

            //Create User=Admin with password=123456

            var user = new MyUser();

            user.UserName = name;
            var adminresult = UserManager.Create(user, password);

            //Add User Admin to Role Admin

            if (adminresult.Succeeded)
            {
                var result = UserManager.AddToRole(user.Id, name);
            }

            base.Seed(context);
        }
    }

每当我试图脚手架时，我都会附上这个错误 1：
