Consume wcf service with netTcpBinding in unity

I am trying to consume wcf service with nettcpbinding in my unity3d application but it gives an error of

Error: Exception has been thrown by the target of an invocation.

My code is:

  private void runService()
     {
         string result = "";
         string _uri = "net.tcp://localhost/netTcpService/NetTcpService.svc";
         Uri uri = new Uri(_uri);
 
         try
         {
             EndpointIdentity id = EndpointIdentity.CreateDnsIdentity("my-pc");
             var binding = new NetTcpBinding();
             binding.Security.Mode = SecurityMode.Message;
             binding.Security.Message.ClientCredentialType = MessageCredentialType.None;
             binding.SendTimeout = TimeSpan.FromMilliseconds(10);
 
             EndpointAddress address = new EndpointAddress(uri, id);
             ChannelFactory<INetTcpService> channel = new ChannelFactory<INetTcpService>(binding, address);
             channel.Credentials.ServiceCertificate.Authentication.CertificateValidationMode = X509CertificateValidationMode.None;
             INetTcpService client = channel.CreateChannel();
             result = client.InsertValueInTable();
         }
         catch (Exception ex)
         {
             result = ex.Message;
             Debug.Log(ex.Message);
             Debug.Log(ex.StackTrace);
             Debug.Log(ex.TargetSite);
             Debug.Log(ex.ToString());
         }
         Debug.Log("RESULT: " + result);
         //
     }

In assets I added System.ServiceModel.dll. above service get call from normal windows form application. Service with wshttpbinding(transport security mode) works in unity3d. How can i consume netTcpBinding base service in unity3d..
