更新到实体框架6后，我的ajax调用不起作用

Question

I am making a wedding website. After realizing I needed to update to entity framework 6 my Controller stopped working. I am using ajax call to see if user has allready logged in and then he doesn't need to log in each time he/she has been away.

I get blablabla.Table does not contain a defintion for "LoggedIn"

This worked before I updated to entityframework 6..... why doesn't it work now?

This is my code

Controller:

        public ActionResult Login(Table u)
        {
            // this action is for handle post (login)
            if (ModelState.IsValid) // this is check validity
            {
                using (LoginEntities dc = new LoginEntities())
                {
                    var v = dc.Tables.Where(a => a.Username.Equals(u.Username) && a.PassWord.Equals(u.PassWord)).FirstOrDefault();
                    if (v != null)
                    {
                        FormsAuthentication.SetAuthCookie(u.Username, true);
                        u.LoggedIn = true;
                        return Json(u);
                    }
                    else
                    {

                        u.LoggedIn = false;
                        u.Message = "You have entered the wrong password, please try again!";
                        return Json(u);



                    }
                }
            }
            return View(u);
        }
    }

}

Script:

$("#LoginForm").submit(function (event) {

    event.preventDefault();
    var url = $(event.target).attr("action");
    //var username = $("#Username");
    var model = $(event.target).serialize();
    //console.log(model);
    console.log(url);
    $.ajax({

        url: url,
        data: model,
        type:"POST",
        success: function (response) {
            console.log("bla");
            if (response.LoggedIn) { window.location = "/Home/Index" } else
            { alert(response.Message); }
        }

    });

});

Class:

    public partial class Table
    {
        public int UserID { get; set; }
        public string Username { get; set; }
        public string PassWord { get; set; }
    }
}

In your code you have this line:

u.LoggedIn = true;

The variable u is of type Table that has no property called LoggedIn . The error is nothing to do with entity framework.

Table is a partial class though so may have been extended somewhere else previously.
