WCF System.InvalidOperationException

Question

我收到以下消息的異常：

服務“ ATPhoneControllerWinService.WCFService”的應用程序端點（非基礎結構）為零。 這可能是因為沒有為您的應用程序找到配置文件，或者是因為在配置文件中找不到與服務名稱匹配的服務元素，或者因為在服務元素中未定義端點。

服務：App.config：

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
    <startup> 
        <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5" />
    </startup>
  <system.serviceModel>
    <services>
      <service name="ATPhoneControllerWinService.WCFService">
        <endpoint address="net.pipe://localhost/ATPipe" 
                  binding="netNamedPipeBinding"
                  contract="ATPhoneControllerWinService.IWCFService" 
        />
      </service>
    </services>
  </system.serviceModel>
</configuration>

客戶端App.config：

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
    <startup> 
        <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5" />
    </startup>
  <system.serviceModel>
    <client>
      <endpoint
         address  = "net.pipe://localhost/ATPipe"
         binding  = "netNamedPipeBinding"
         contract = "ATPhoneControllerWinService.IWCFService"
         />
    </client>
  </system.serviceModel>
</configuration>

文件位於不同的VS2012項目中（一個是WPF，另一個是Windows（不是WCF）服務）。 我是WCF的新手，我不知道自己缺少什么。

好的，現在我沒有異常，可以通過編程添加端點來解決它：

host = new ServiceHost(typeof(WCFService), new Uri("net.pipe://localhost/ATPipe"));
            host.AddServiceEndpoint(typeof(IWCFService), new NetNamedPipeBinding(), "net.pipe://localhost/ATPipe");
            host.Open();

問題仍然存在，我應該將xml配置文件放在應用程序配置文件中，還是上面的配置有什么問題^？

解決問題的最簡單方法是使用WCF配置編輯器 （Visual Studio附帶）來添加端點。 只需定義端點並與您的配置進行比較即可。

這樣，您就不必通過尋找拼寫問題或放置錯誤的定義來動腦子。
