WCF-NetNamedPipe的的ChannelFactory

更新20121214 與衝突的服務的開發者協商，他們使用net.pipe：// ECHONET作爲服務地址，和使用DuplexChannelFactory。爲什麼它會阻止我的管道？WCF-NetNamedPipe的的ChannelFactory

問：

我有一個非常簡單的WCF應用程序。服務和客戶端通過NetNamedPipe通信。但奇怪的是，有些機器可能是因爲其他軟件，導致ChannelFactory開始調用Service的其他軟件，拋出一個異常：System.ServiceModel.ProtocolException。

我怎麼知道哪個應用程序能夠捕獲我的WCF消息，以及我應該如何避免這個問題。

這裏是例外：

System.ServiceModel.ProtocolException: The requested upgrade is not supported by 'net.pipe://localhost/xxxx/xxxx'. This could be due to mismatched bindings (for example security enabled on the client and not on the server) 

Server stack trace:

    xxx.xxxxx.Communication.xxxComClient.ActionClientRegisterOnlineClientInfo(IxxxComClientService channel) 
    xxx.xxxxx.Communication.xxxComClient.ActionReceivedClientOnline(EndpointAddress endpoint)

這裏是我的代碼」

using (var host = new ServiceHost(typeof(StringReverser), new[] { new Uri("net.pipe://localhost") })) 
{ 
    host.AddServiceEndpoint(typeof(IStringReverser), new NetNamedPipeBinding(), "PipeReverse"); 
    host.Open(); 

    Console.WriteLine("Service is available. Press <ENTER> to exit."); 
    Console.ReadLine(); 

    host.Close(); 
    }

Console.WriteLine("pipeProxy Created."); 

while (true) 
{ 
    var str = Console.ReadLine(); 
    Console.WriteLine("pipe: " + pipeProxy.ReverseString(str));

更多的例外細節？ – carlosfigueira

好吧，我更新我的問題。 – GeminiYellow

如果說它在某些機器上可用，但在其他機器上卻不可用，那麼可能不會支持默認的'NetNamedPipeBinding'使用的安全模型的機器（基於錯誤消息）。嘗試使用新的NetNamedPipeBinding（NetNamedPipeSecurityMode.None）創建綁定，以查看此問題是否消失。 – carlosfigueira

b1。該服務是Windows服務器上的主機，以管理員身份運行
b2。該服務，將net.pipe：// echonet設置爲他的地址
b3。我的服務，是自主機上，運行作爲localuser

windowsservice> localuser 所以，namedpipe會重定向到該服務。

s1。停止服務
s2。改變我的服務主機，讓它主機上 windowsservice。
