与WCF客户端在同一程序集中的EndpointNotFoundException

我在我的WPF应用程序中托管一个WCF服务，并希望在同一程序集中使用它(虽然在另一个实例中)。为了依赖注入的缘故，我用一个已经创建的服务实现实例来调用ServiceHost.Open。

合同与服务实现

[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;
    }
}

          </security>

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

ServiceHost创建

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

打开ServiceHost后，它监听端口61000(通过netstat检查)。虽然我不需要它(因为我自己创建了一个实现IService的客户端)，但我测试了创建一个服务引用，它工作了。

然而，我的服务实现看起来是这样的:

public class ServiceClient : ClientBase<IService>, IService
{
    public ServiceClient(string endpointConfigurationName, EndpointAddress remoteAddress) :
            base(endpointConfigurationName, remoteAddress)
    {
    }
    public PartnerInfo GetPartnerInfo()
    {
        return Channel.GetPartnerInfo();
    }
}

当我这样调用它时，在同一台机器上有另一个服务托管实例，抛出EndpointNotFoundException:

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")));

我是否错过了ServiceClient的实现，因为我在同一程序集中拥有服务和客户端，因此不想在Visual Studio中创建服务引用?

我测试了创建服务引用的整个过程。这也行不通。我也仔细检查了我的防火墙规则。下面是异常消息:

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.

更新2

出于测试目的，我创建了第二个wsHttpBinding端点。这个在我的浏览器中可以访问，所以服务已经启动并运行。
