解决方法

务必：

>首先创建用户记录
>调用WebMatrix以创建用户帐户.

以下是我的代码,它解决了您遇到的同一问题：

public ActionResult SignUp(SignUpModel model)
    {
        if (ModelState.IsValid)
        {
            using (MorphometryContext context = new MorphometryContext())
            {
                User user = new User
                {
                    Email = model.Email,FirstName = model.FirstName,LastName = model.LastName,Username = model.UserName
                };
                context.Users.Add(user);
                context.SaveChanges();
            }

            // Attempt to register the user
            try
            {
                WebSecurity.CreateAccount(model.UserName,model.Password);
            }
            catch (MembershipCreateUserException e)
            {
                ModelState.AddModelError("",ErrorCodeToString(e.StatusCode));
                return View();
            }

            WebSecurity.Login(model.UserName,model.Password);
            return RedirectToAction("Index","Projects");
        }

此外,您不希望Respoonse.Redirect到.cshtml文件.相反,您应该返回RedirectToAction并传入Action和Controller名称.
