C# ASP.Net标识自定义字段在创建用户时丢失值

因此，我对MVC5、EF6和ASP.Net标识有一个有趣的问题。我已向ApplicationUser添加了一个自定义字段，但当我尝试使用UserManager.CreateAsync（）创建新用户时，出现以下错误：

“ApplicationUser”上的“IsConfiged”属性无法设置为“null”值。必须将此属性设置为“System.Boolean”类型的非空值

注意：调试时，user.IsConfirmed不为null的值应为false

有关守则如下：

ApplicationUser user = new ApplicationUser()
{
     UserName = model.UserName,
     Email = model.Email,
     ConfirmationToken = confirmationToken,
     IsConfirmed = false
};

IdentityResult result = await UserManager.CreateAsync(user, model.Password);

以及应用程序用户的定义：

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'. ]
