如何从控制台应用程序连接到Windows通用应用程序StreamSocket？

Question

我正在通过Windows通用应用程序侦听连接，并希望通过Windows控制台应用程序连接到该应用程序。我已经完成了一些我认为应该连接的基本代码，但是我从控制台应用程序中收到了一个超时错误。

{"A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond 192.168.0.5:1771"} 

Windows通用应用程序甚至不会进入连接接收功能。

服务器（UWP）：

public async void SetupServer() 
    { 
     try 
     { 
      //Create a StreamSocketListener to start listening for TCP connections. 
      Windows.Networking.Sockets.StreamSocketListener socketListener = new Windows.Networking.Sockets.StreamSocketListener(); 

      //Hook up an event handler to call when connections are received. 
      socketListener.ConnectionReceived += SocketListener_ConnectionReceived; 

      //Get Our IP Address that we will host on. 
      IReadOnlyList<HostName> hosts = NetworkInformation.GetHostNames(); 
      HostName myName = hosts[3]; 

      //Assign our IP Address 
      ipTextBlock.Text = myName.DisplayName+":1771"; 
      ipTextBlock.Foreground = new SolidColorBrush(Windows.UI.Color.FromArgb(255,0,255,0)); 

      //Start listening for incoming TCP connections on the specified port. You can specify any port that' s not currently in use. 
      await socketListener.BindEndpointAsync(myName, "1771"); 
     } 
     catch (Exception e) 
     { 
      //Handle exception. 
     } 
    } 

客户端（控制台应用程序）：

static void Main(string[] args) 
    { 
     try 
     { 
      byte[] data = new byte[1024]; 
      int sent; 
      string ip = "192.168.0.5"; 
      int port = 1771; 
      IPEndPoint ipep = new IPEndPoint(IPAddress.Parse(ip), port); 
      TcpClient client = new TcpClient(); 
      client.Connect(ipep); //**************Stalls HERE************ 
      using (NetworkStream ns = client.GetStream()) 
      { 
       using (StreamReader sr = new StreamReader(ns)) 
       { 
        using (StreamWriter sw = new StreamWriter(ns)) 
        { 
         sw.WriteLine("Hello!"); 
         sw.Flush(); 
         System.Threading.Thread.Sleep(1000); 
         Console.WriteLine("Response: " + sr.ReadLine()); 
        } 
       } 
      } 
     } 
     catch (Exception e) 
     { 

     } 
    }

我已经测试过在我的身边你的代码，它可以很好地工作。所以你的代码没有问题。但是我可以通过在同一设备上运行服务器和客户端来重现您的问题，客户端将抛出与上面显示的相同的异常。所以请确保你从另一台机器连接。我们无法从运行在同一台计算机上的其他应用或进程连接到uwp应用StreamSocketListener，这是不允许的。即使免除loopback。

另请确保已启用Internet(Client&Server)capability。在客户端上，您可以成功地ping服务器192.168.0.5。
