MembershipProvider自定義 - 使用EF POCO保存時出錯4.1

我正在自定義類MembershipProvider。MembershipProvider自定義 - 使用EF POCO保存時出錯4.1

導航到Asp.net網站管理工具時，可以正常列出用戶。

List users

下面的代碼是負責在數據庫中輸入用戶：

public User CreateUser(string username, string password, string email) 
{ 
    using (var db = new DataContext()) 
    { 
     var user = new User 
         { 
          Name = username 
          , 
          Password = password 
          , 
          Gender = Gender.Unknown 
          , 
          IsApproved = false 
          , 
          IsBlock = false 
         }; 

     db.Users.Add(user); 

     db.SaveChanges(); 
     return GetUser(username); 
    } 
}

在線路錯誤db.SaveChanges();

當試圖註冊新用戶時，出現以下錯誤：

** Asp.net管理工具**錯誤**

我設法解決。錯誤發生在InnerException屬性中。這個問題只是一個日期格式;
