How to solve NotImplementedException during using WCF Duplex net.tcp binding?

Full exception message:

NotImplementedException: The requested feature is not implemented. System.ServiceModel.DuplexClientBase`1[TChannel].CreateChannel () System.ServiceModel.ClientBase`1[TChannel].get_InnerChannel () System.ServiceModel.ClientBase`1[TChannel].Open () Assets.ClientProxies.Test.Start () (at Assets/ClientProxies/Test.cs:23)

Appears after i'm trying to open connection.

Simple WCF service without duplex, works perfectly, please help me to make duplex work, the same code on .NET works fine.

Code listing:

 using System;
 using System.ServiceModel;
 using UnityEngine;
 
 namespace Assets.ClientProxies
 {
     public class Test : MonoBehaviour, IMyServiceCallback
     {
         private GameObject _obj;
         // Use this for initialization
         void Start ()
         {
             Debug.Log("START");
                
             var client = new MyServiceClient(new InstanceContext(this),
                                          new NetTcpBinding(SecurityMode.None),
                                          new EndpointAddress(string.Format("net.tcp://localhost:9000/MyService/Main")));
 
             client.Open(); //<- Error here
             Debug.Log(client.GetNumber());
             Debug.Log("FINE");
         }
     
         // Update is called once per frame
         void Update () {
     
         }
 
         public void Hello()
         {
             throw new NotImplementedException();
         }
 
         public IAsyncResult BeginHello(AsyncCallback callback, object asyncState)
         {
             throw new NotImplementedException();
         }
 
         public void EndHello(IAsyncResult result)
         {
             throw new NotImplementedException();
         }
     }
 }
