与同一程序集中的WCF客户端的EndpointNotFoundException

Question

I'm hosting a WCF Service in my WPF app and want to consume it within the same assembly (in another instance, though). For the sake of dependency injection I'm calling ServiceHost.Open with an already created instance of my service implementation.

Contract and Service implementation

[ServiceContract(ProtectionLevel = ProtectionLevel.EncryptAndSign)]
public interface IService
{
    [OperationContract]
    PartnerInfo GetPartnerInfo();
}

[ServiceBehavior(InstanceContextMode = InstanceContextMode.Single)]
public class Service : IService
{
    private IpService _ipService;

    public Service(IpService ipService)
    {
        _ipService = ipService;
    }

    public PartnerInfo GetPartnerInfo()
    {
        var info = new PartnerInfo();
        info.Address = _ipService.GetLocalIpAddress();

        return info;
    }
}

App.config

                  contract="Project.WebService.IService">
          <identity>
            <servicePrincipalName value="Project.WebService.Service"/>
          </identity>

          </baseAddresses>
        </host>
      </service>
    </services>

          </security>

        </binding>
      </netTcpBinding>
    </bindings>
    <client>
      <endpoint
        binding="netTcpBinding"
        bindingConfiguration="NetTcpBinding_IService"
        contract="Project.WebService.IService"
        name="NetTcpBinding_IService">

    </client>
  </system.serviceModel>
</configuration>

ServiceHost creation

_serviceHost = new ServiceHost(_Service);
_serviceHost.Open();

After opening the ServiceHost , it listens on Port 61000 (checked via netstat). Altough I don't need it (because I created a client implementing IService myself), I tested creating a service reference and it worked.

However, my service implementation looks like this:

public class ServiceClient : ClientBase<IService>, IService
{
    public ServiceClient(string endpointConfigurationName, EndpointAddress remoteAddress) :
            base(endpointConfigurationName, remoteAddress)
    {
    }

    public PartnerInfo GetPartnerInfo()
    {
        return Channel.GetPartnerInfo();
    }
}

And when I'm calling it this way, with another service hosting instance on the same machine, an EndpointNotFoundException is thrown:

Uri baseUri = new Uri("net.tcp://<IPAdress>:61000");
Uri uri = new Uri(baseUri, "Project/Service.svc");

// Spn identity is only here for testing purposes, doesn't work either way
return new ServiceClient("NetTcpBinding_IService", new EndpointAddress(uri, EndpointIdentity.CreateSpnIdentity("NetTcpBinding_IService")));

Am I missing something on my implementation of the ServiceClient as I have both service and client in the same assembly and therefore don't want to create a service reference in Visual Studio?

Update

I tested the whole process creating a Service Reference. This doesn't work either. I also double-checked my firewall rules. Here is the exception message:

There was no endpoint listening at net.tcp://192.168.200.29:61000/Project/Service.svc that could accept the message. This is often caused by an incorrect address or SOAP action. See InnerException, if present, for more details.

Update 2

For testing purposes, I created a second wsHttpBinding Endpoint. This one is reachable in my browser, so the service is up and running.

Answer 1

After hours of debugging, I solved the (quite simple) issue myself:

As it turned out, the service URL wasn't net.tcp://localhost:61000/Project/Service.svc but net.tcp://localhost:61000/Project/Service.svc/endpoint0 .

After removing the "endpoint0" from my endpoint configuration, the connection went well:

<endpoint address=""
          binding="netTcpBinding"
          bindingConfiguration="NetTcpBinding_IService"
          contract="Project.WebService.IService">
  <!-- -->
</endpoint>
