Question

Editorial interfaz

[ServiceContract]
    public interface IPublisherInterface
    {
        [OperationContract(IsOneWay = false)]
        void Publish(MessageClass e, string topicName);

    }

Subscriber Interface

[ServiceContract(CallbackContract = typeof(IPublisherInterface))]
    public interface ISubscriberInterface
    {
        [OperationContract]
        void Subscribe(string topicName);

        [OperationContract]
        void UnSubscribe(string topicName);
    } 

Programa de abonado

class Program
    {
        static void Main(string[] args)
        {
            DuplexChannelFactory<ISubscriberInterface> namedPipeFactory =
               new DuplexChannelFactory<ISubscriberInterface>(
                    new InstanceContext(new PublisherService()),
                  new NetNamedPipeBinding(),
                  new EndpointAddress("net.pipe://localhost/Sub"));

            ISubscriberInterface pipeProxy = namedPipeFactory.CreateChannel();
            pipeProxy.Subscribe("name");

            //SubscriberForm f = new SubscriberForm(pipeProxy);
            //f.ShowDialog();
        }
    }

¿Por qué recibo este mensaje?

The message with Action 'http://tempuri.org/ISubscriberInterface/Subscribe' cannot be
 processed at the receiver, due to a ContractFilter mismatch at the EndpointDispatcher. 
This may be because of either a contract mismatch (mismatched Actions between sender and 
receiver) or a binding/security mismatch between the sender and the receiver.  Check that
 sender and receiver have the same contract and the same binding (including security 
requirements, e.g. Message, Transport, None)."

Este es mi anfitrión

class Program
    {
        static void Main(string[] args)
        {
            ServiceHost _publisherServiceHost = new ServiceHost(typeof(PublisherService), new Uri[] { new Uri("net.pipe://localhost/") });
            _publisherServiceHost.AddServiceEndpoint(
                    typeof(IPublisherInterface),
                    new NetNamedPipeBinding(),
                    "Pub");
            _publisherServiceHost.Open();

            ServiceHost _subscriberServiceHost = new ServiceHost(typeof(PublisherService), new Uri[] { new Uri("net.pipe://localhost/") });
            _subscriberServiceHost.AddServiceEndpoint(
                    typeof(IPublisherInterface),
                    new NetNamedPipeBinding(),
                    "Sub");
            _subscriberServiceHost.Open();

            Console.WriteLine("Server is Running.");
            Console.ReadLine();
        }
    }

Answer 1

Creo, su problema está aquí:

_subscriberServiceHost.AddServiceEndpoint(
                typeof(IPublisherInterface),
                new NetNamedPipeBinding(),
                "Sub");

El host de servicio de abonado se ha creado usando IPublisherInterface contrato, que está mal. Debe ser ISubscriberInterface en lugar

Answer 2

¿Está seguro con la segunda abertura anfitrión? ¿No debería ser:

    ServiceHost _subscriberServiceHost = new ServiceHost(typeof(SubscriberService), new Uri[] { new Uri("net.pipe://localhost/sub") });
    _subscriberServiceHost.AddServiceEndpoint(
            typeof(ISubscriberInterface),
            new NetNamedPipeBinding(),
            "Sub");
    _subscriberServiceHost.Open();

Estoy adivinando los nombres, pero supongo que, probablemente, el nombre que se le da a su aplicación ISubscriberInterface.
