求助 WCF TCP双工通信时遇到的问题 向 ChannelFactory 提供的 InstanceContext 包含未实现 CallbackContract

Question

异常信息 
向 ChannelFactory 提供的 InstanceContext 包含未实现 CallbackContractType“CT_CLIENT.ClientProxy.IServiceCallback”的 UserObject。Host 端信息namespace IE_SERVICE
{
    public interface IClientCallBack
    {
        [OperationContract(IsOneWay = true)]
        [System.ServiceModel.ServiceKnownTypeAttribute(typeof(object[]))]
        void SendInfo(CN_MODEL.Info info);        [OperationContract(IsOneWay = true)]
        [System.ServiceModel.ServiceKnownTypeAttribute(typeof(object[]))]
        void UpdateCurRefreshTime(int id, int curRefreshCount, DateTime curRefreshTime, string content,int userid);        [OperationContract(IsOneWay = true)]
        [System.ServiceModel.ServiceKnownTypeAttribute(typeof(object[]))]
        void CloseSameClient();    }
}
namespace IE_SERVICE
{
    [ServiceContract(SessionMode = SessionMode.Required, CallbackContract = typeof(IClientCallBack))]    
    public interface IService
    {
       [OperationContract]
       string GetCityId(string cityName, object[] obj);
     }
}
客户端实现:
namespace CT_CLIENT
{
    public partial class Form2 : FrmBase, IE_SERVICE.IClientCallBackpublic void SendInfo(Info info)
        {
            //具体代码
        }public void UpdateCurRefreshTime(int id, int curRefreshCount, DateTime curRefreshTime, string content, int userid)
{
    //具体代码
}
        public void CloseSameClient()
        {
           //具体代码        }private void bttrial_Click(object sender, EventArgs e)
{
     string cId = Proxy.GetCityId("郑州");//在这里出错
}
}public static ProxyFacade Proxy
        {
            get
            {
                if (proxy == null)
                {
                    //proxy = new ProxyFacade(new InstanceContext(new FrmMain()));
                    proxy = new ProxyFacade(new InstanceContext(proxyObj));
                    return proxy;
                }
                else
                {
                    
                    return proxy;
                }
            }
        }
 public ProxyFacade(InstanceContext callback)
        {
            if (proxy == null)
                proxy = new ClientProxy.ServiceClient(callback);
            else
            {
                proxy.Abort();
                proxy.Close();
                proxy = null;
                proxy = new ClientProxy.ServiceClient(callback);
            }        }
