C# ASP.NET MVC 5标识中的空引用

我对ASP.NET MVC个人用户帐户默认模板有问题。我在ActionResult寄存器中获得空引用，但modelstate有效。我已经用同样的代码创建了另一个项目，它工作起来很有魅力

在这个项目中它不工作这是我的代码你能帮我吗

我的型号：

     public class User : IdentityUser
    {
        //public string Title { get; set; } // mevr. of mr.
        //public string FirstName { get; set; }
        //public string LastName { get; set; }
        //public System.DateTime? Birthdate { get; set; }

        public async Task<ClaimsIdentity> GenerateUserIdentityAsync(UserManager<User> manager)
        {
            // Note the authenticationType must match the one defined in CookieAuthenticationOptions.AuthenticationType
            var userIdentity = await manager.CreateIdentityAsync(this, DefaultAuthenticationTypes.ApplicationCookie);
            // Add custom user claims here
            return userIdentity;
        }

有关额外信息的我的视图：

@model PortOfTroy.Models.RegisterViewModel
@{
    ViewBag.Title = "Register";
}

<h2>@ViewBag.Title.</h2>

@using (Html.BeginForm("Register", "Account", FormMethod.Post, new { @class = "form-horizontal", role = "form" }))
{
    @Html.AntiForgeryToken()
    <h4>Create a new account.</h4>
    <hr />
    @Html.ValidationSummary("", new { @class = "text-danger" })
    <div class="form-group">
        @Html.LabelFor(m => m.Email, new { @class = "col-md-2 control-label" })
        <div class="col-md-10">
            @Html.TextBoxFor(m => m.Email, new { @class = "form-control" })
        </div>
    </div>
    <div class="form-group">
        @Html.LabelFor(m => m.Password, new { @class = "col-md-2 control-label" })
        <div class="col-md-10">
            @Html.PasswordFor(m => m.Password, new { @class = "form-control" })
        </div>
    </div>
    <div class="form-group">
        @Html.LabelFor(m => m.ConfirmPassword, new { @class = "col-md-2 control-label" })
        <div class="col-md-10">
            @Html.PasswordFor(m => m.ConfirmPassword, new { @class = "form-control" })
        </div>
    </div>
    <div class="form-group">
        <div class="col-md-offset-2 col-md-10">
            <input type="submit" class="btn btn-default" value="Register" />
        </div>
    </div>
}

}

@model-PortOfTroy.Models.RegisterViewModel

更新好的一个 堆栈跟踪

我终于解决了（在你们的帮助下）。我在我的公共类User:IdentityUser中有一些自定义实现，我确实对它们进行了注释，但在我的Viewmodels注册和登录中没有这样做！所以，是的，模型期望一些不再存在的数据。我要感谢@Jake，他提出了UserManager上的自定义实现。
