WCF继承合同和回调合同

Question

我有一个测试继承合同和回调合同的测试项目。

更新1 ：我使用接口implamantations更新了所有主题

这是可能的，但是当我尝试它时，它会失败。

class Program
    {
        static void Main(string[] args)
        {
            ServiceHost Service_IServer = new ServiceHost(new ServiceImplemantation(), new Uri(@"net.tcp://localhost:8080/"));
            Service_IServer.AddServiceEndpoint(typeof(IService), new NetTcpBinding(), "Service");
            Service_IServer.Open();
            ServiceHost Service_I_IP = new ServiceHost(new IPImplemantation(), new Uri(@"net.tcp://localhost:8080/"));
            Service_I_IP.AddServiceEndpoint(typeof(I_IP), new NetTcpBinding(), "Service");
            Service_I_IP.Open();
            Console.ReadLine();
        }
    }
    [ServiceContract]
    public interface I_IP
    {
        [OperationContract]
        string GetIP();
    }
    [ServiceContract]
    public interface IService : I_IP
    {
        [OperationContract]
        void ImTheServer_Print();
    }
    //
    //
    //
    //
    [ServiceBehavior(InstanceContextMode = InstanceContextMode.Single)]
    public class IPImplemantation : I_IP
    {
        public string GetIP()
        {
            return "1.2.3.4";
        }
    }
    [ServiceBehavior(InstanceContextMode = InstanceContextMode.Single)]
    public class ServiceImplemantation : IPImplemantation, IService
    {
        public void ImTheServer_Print()
        {
            Console.WriteLine("ImTheServer_Print");
        }
    }

错误：

'net.tcp：// localhost：8080 / Service'中的ChannelDispatcher与合同'“I_IP”'无法打开其IChannelListener。

确保将其装饰为OneWay。

[OperationContract(IsOneWay = true)]
void GetIP();
