Asp. net MVC проверка не работает, скорее выдает исключение

Question

Я пытаюсь создать форму регистрации для MVC веб-приложения, но по какой-то причине проверка не работает, компилятор пропускает if(modelstate.isvalid), а затем выдает исключение на password hashing, поскольку значение null .

Я на самом деле пытаюсь скопировать код из другого проекта, так как у меня были проблемы с обновлением локальных данных, код почти такой же, но проверка не работает, я не знаю, могу ли я я не знаю о какой-то другой проблеме

Это контроллер

namespace TestApp6.Controllers
{
    public class UserController : Controller
    {
        //Registration action
        [HttpGet]

        public ActionResult Registration()
        {
            return View();
        }

        //Registration POST action
        [HttpPost]
        [ValidateAntiForgeryToken]

        public ActionResult Registration([Bind(Exclude = "IsEmailVerified,ActivationCode")] User user)
        {
            bool Status = false;
            string message = "";

            //
            // Model Validation
            if (ModelState.IsValid)
            {





                // Generate Activation code
                user.ActivationCode = Guid.NewGuid();


                //Password hashing
                user.Password = Crypto.Hash(user.Password);
                user.ConfirmPassword = Crypto.Hash(user.ConfirmPassword);

                user.IsEmailVerifed = false;




                //Save data to database

                using (MyDatabaseEntities dc = new MyDatabaseEntities())
                {
                    dc.Users.Add(user);
                    dc.SaveChanges();

                    // send Email to the user

                    //SendVerificationSendLink(user.EmailID, user.ActivationCode.ToString());
                    //message = "Registration successfully done.Account activation link" +
                    //    " has been sent to your email id:" + user.EmailID;
                    //Status = true;
                }



            }

            else
            {
                message = "Invalid Request";
            }

            ViewBag.Message = message;
            ViewBag.Status = Status;
            return View(user);



        }
