ASP.NET身份自定义字段丢失创建用户的值

Question

所以，我对MVC5，EF6和ASP.NET身份有一个有趣的问题。我已经在Applicationuser中添加了一个自定义字段，但是当我尝试使用usermanager.createasync（）创建新用户时，我会收到以下错误：

无法将"应用程序用户"上的"确认"属性设置为" null"值。您必须将此属性设置为" system.boolean"类型的非零值。

注意：当调试user.isconfirned为null时，其值为false。

所讨论的代码如下：

ApplicationUser user = new ApplicationUser()
{
     UserName = model.UserName,
     Email = model.Email,
     ConfirmationToken = confirmationToken,
     IsConfirmed = false
};
IdentityResult result = await UserManager.CreateAsync(user, model.Password);

和aplicationuser的定义：

public class ApplicationUser : IdentityUser
{
     public string Email { get; set; }
     public string ConfirmationToken { get; set; }
     public bool IsConfirmed { get; set; }
}

最后，堆栈跟踪：

[ConstraintException: The 'IsConfirmed' property on 'ApplicationUser' could not be set to a 'null' value. You must set this property to a non-null value of type 'System.Boolean'. ]

好吧，所以...有点尴尬，但是失败的原因是我已经存储了试图抓住空字段值的过程，因为我从未在测试之前清除用户存储并使用相同的用户名。在这个项目上的努力之间，我已经休息了大约两个星期，但仍然……糟糕。：P感谢所有帮助我完成此工作的耐心灵魂。
