내가 그렇게 같은 net.tcp WCF 서비스를 만든

Question

서비스 참조로 net.tcp 추가 할 수 없습니다 : 여기

const string tcpUri = "net.tcp://localhost:9038"; 
var netTcpHost = new WebServiceHost(typeof(DashboardService), new Uri(tcpUri)); 
netTcpHost.AddServiceEndpoint(typeof(IDashboardService), new NetTcpBinding(), 
                  "/dashboard"); 

netTcpHost.Open(); 

Console.WriteLine("Hosted at {0}. Hit any key to shut down", tcpUri); 
Console.ReadKey(); 

netTcpHost.Close(); 

내 IDashboardService 및 DashboardSerivce 정의이다 : 그러나

[ServiceContract] 
public interface IDashboardService 
{ 
    [OperationContract] 
    PositionDashboard Loader(); 
} 

[ServiceBehavior(InstanceContextMode = InstanceContextMode.PerCall)] 
public class DashboardService : IDashboardService 
{ 
    public PositionDashboard Loader() 
    { 
     ... 
    } 
} 

을 때 WCF 테스트 클라이언트로 서비스에 연결하려고하면 다음 오류가 발생합니다.

Error: Cannot obtain Metadata from net.tcp://localhost:9038/dashboard 
The socket connection was aborted. This could be caused by an error processing your 
message or a receive timeout being exceeded by the remote host, or an underlying 
network resource issue. Local socket timeout was '00:04:59.9890000'. An existing 
connection was forcibly closed by the remote host 

Answer 1

오류가 발생했습니다. "메타 데이터를 가져올 수 없습니다 ..."을 명시 적으로 언급 했으므로 TCP Mex Endpoint가 있는지 확인할 가치가 있습니다. 이 설정에서 모양은 다음과 같습니다

<endpoint address="mex" binding="mexTcpBinding" contract="IMetadataExchange" /> 

을 다른 방법으로, 당신은 당신이 다음하고 싶은 경우 System.ServiceModel.Discovery를 참조하는 다음 코드는 다음과 같아야 필요

const string tcpUri = "net.tcp://localhost:9038"; 
using (var netTcpHost = new WebServiceHost(
    typeof(DashboardService), 
    new Uri(tcpUri))) 
{ 
    netTcpHost.Description.Behaviors.Add(new ServiceMetadataBehavior()); 
    netTcpHost.AddServiceEndpoint(
     typeof(IMetadataExchange), 
     MetadataExchangeBindings.CreateMexTcpBinding(), 
     "mex"); 
    netTcpHost.AddServiceEndpoint(
     typeof(IDashboardService), 
     new NetTcpBinding(), 
     "dashboard"); 

    netTcpHost.Description.Behaviors.Add(new ServiceDiscoveryBehavior()); 
    netTcpHost.AddServiceEndpoint(new UdpDiscoveryEndpoint()); 

    netTcpHost.Open(); 
    Console.WriteLine("Hosted at {0}. Hit any key to shut down", tcpUri); 
    Console.ReadLine(); 

    netTcpHost.Close(); 
}
