Неизвестная ошибка для ответа Wcf Rest -Get C #

У меня есть WCF, остальные получают сервис для получения всех пакетов из базы данных: 

[ServiceContract]
public interface IPackages
{
    [OperationContract]
    [WebGet]
    List<WsPackage> GetAllPackages();
}

*** Это мой класс WsPackage: 

 [DataContract]
public class WsPackage : WsEntities
{
    [DataMember]
    public string EntryPeriod { get; set; }
    [DataMember]
    public string Phase { get; set; }
    [DataMember]
    public int? EntryPeriodId { get; set; }
    [DataMember]
    public int? PhaseId { get; set; }
    [DataMember]
    public packStatus Status { get; set; }
    [DataMember]
    public object EffectiveLockOrProtect { get; set; }
    [DataMember]
    public packLock EffectiveLockOrProtectLocal { get; }
}

Реализация этого сервисахорошо работает, и если я сделаю точку останова, я получу правильный результат:

enter image description here

  • Но если я позволю точкам останова, я получубесконечный цикл, несмотря на то, что у меня нет условий или чего-либо до бесконечности, весь код в порядке!

* И это исключение из WCF traceLog:

  • Сначала я пытаюсь добавить закрытый набор для свойства EffectiveLockOrProtectLocal:

    [DataMember] public packLock EffectiveLockOrProtectLocal {get;приватный набор;}

Но всегда у меня возникает одна и та же ошибка.

  • Затем я пытаюсь изменить свой класс WsPackage (я комментирую свойство EffectiveLockOrProtectLocal и создаю IgnoreDataMemberдля свойства EffectiveLockOrProtect: 

         [IgnoreDataMember]
public object EffectiveLockOrProtect { get; set; }
   //[DataMember]
//public packLock EffectiveLockOrProtectLocal { get; }

    С этим изменением у меня хороший ответ: 84 значения.

Так как я могу исправить эту проблему, чтобы работать сдва свойства: EffectiveLockOrProtect и EffectiveLockOrProtectLocal?

Я нашел решение, сначала я должен добавить набор в свойство EffectiveLockOrProtectLocal: 

 [DataMember]        
    public packLock EffectiveLockOrProtectLocal { get; set; }

И добавить IgnoreDataMemberAttribute в свойство EffectiveLockOrProtect: 

    [IgnoreDataMember]
    public object EffectiveLockOrProtect { get; set; }

Что-то не так с сериализацией и десериализацией.
Есть ли у вас контракты на передачу данных на стороне сервера и на стороне клиента? В противном случае проблемы с сериализацией неизбежны при использовании платформы ORM для возврата данных. По умолчанию DataContract является параметром сериализации по умолчанию. Поэтому, пожалуйста, сохраняйте согласованность данных на стороне клиента и на стороне сервера.
