在WP7中引用WCF時的空配置文件應用

Question

我試圖從WP7應用程序中使用我自己的WCF服務。

在WCF服務

<?xml version="1.0"?> 
<configuration> 

    <system.web> 
    <compilation debug="true"/> 
    </system.web> 
    <system.serviceModel> 
    <services> 

     <service name="mergedServices.MergedService"> 

     <endpoint address="" binding="wsHttpBinding" contract="mergedServices.RelationGeneratorServiceInterface"> 
      <identity> 
      <dns value="localhost" /> 
      </identity> 
     </endpoint> 

     <endpoint address="" binding="wsHttpBinding" contract="mergedServices.keywordSearchServiceInterface"> 
      <identity> 
      <dns value="localhost" /> 
      </identity> 
     </endpoint> 

     <endpoint address="" binding="wsHttpBinding" contract="mergedServices.QAServiceInterface"> 
      <identity> 
      <dns value="localhost" /> 
      </identity> 
     </endpoint> 

     <endpoint address="" binding="wsHttpBinding" contract="mergedServices.CompareWithOnePredicateInterface"> 
      <identity> 
      <dns value="localhost" /> 
      </identity> 
     </endpoint> 

     <endpoint address="" binding="wsHttpBinding" contract="mergedServices.ComparisonServiceInterface"> 
      <identity> 
      <dns value="localhost" /> 
      </identity> 
     </endpoint> 


     <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" /> 
     <host> 
      <baseAddresses> 
      <add baseAddress="http://localhost:8732/Design_Time_Addresses/mergedServices/" /> 
      </baseAddresses> 
     </host> 
     </service> 

    </services> 
    <behaviors> 
     <serviceBehaviors> 
     <behavior> 
      <!-- To avoid disclosing metadata information, 
      set the value below to false and remove the metadata endpoint above before deployment --> 
      <serviceMetadata httpGetEnabled="True"/> 
      <!-- To receive exception details in faults for debugging purposes, 
      set the value below to true. Set to false before deployment 
      to avoid disclosing exception information --> 
      <serviceDebug includeExceptionDetailInFaults="False"/> 
     </behavior> 
     </serviceBehaviors> 
    </behaviors> 
    </system.serviceModel> 

<startup><supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.0"/></startup></configuration> 

當我在一個控制檯客戶參考WCF服務配置文件，客戶端配置文件看起來像這樣：

       </identity> 
      </endpoint> 
     </client> 
    </system.serviceModel> 
</configuration> 

問題是，當我嘗試從WP7項目中使用WCF服務，當我參考服務時，這是配置文件中的內容：

<configuration /> 

，這就是它......... 當我啓動應用程序，將出現以下運行時錯誤：

System.Collections.Generic.KeyNotFoundException was unhandled 
    Message=KeyNotFoundException 
    StackTrace: 
     at System.ThrowHelper.ThrowKeyNotFoundException() 
     at System.Collections.Generic.Dictionary`2.get_Item(String key)

     at MS.Internal.JoltHelper.FireEvent(IntPtr unmanagedObj, IntPtr unmanagedObjArgs, Int32 argsTypeIndex, Int32 actualArgsTypeIndex, String eventName) 

的引用後綁定應該返回config文件，我不確定出了什麼問題，我沒有在IIS上託管WCF，我只是在模擬器上試用WP7應用程序時在後臺運行WCF庫的項目。

Answer 1

我面臨同樣的問題。我所做的是：
1.右鍵單擊服務參考。
2.選擇「配置服務參考...」
3.無需在出現的對話框中更改任何內容。
4.單擊對話框上的「確定」。

這爲我重新生成了「ServiceReferences.ClientConfig」文件。

希望這會有所幫助。

Answer 2

windows phone 7的運行時間是silverlight，它不支持WSHttpBinding。您必須將服務綁定更改爲basicHttpBinding，這是silverlight項目支持的唯一綁定。 :(

的KeyNotFoundException是由於默認綁定（BasicHttpBinding）在服務的綁定列表不存在（僅WSHttpBinding在你的服務中找到）。

如果您不能或不想碰原來WSHttpBinding配置WCF服務，您還可以通過採取適配器設計模式的優勢變通辦法。

我遇到了這個確切的問題，當我開發Windows消耗一個WSHttpBinding WCF服務電話應用程序。最後，我只好實施a dapter WCF服務本身是BasicHttpBinding配置和使用原始WSHttpBinding服務。然後讓Windows Phone應用程序使用適配器服務。

雖然這適配器方法需要一些額外的工作，它仍然是一個優雅的解決方法。

Answer 3

爲了從vs2013上的windows phone 8項目中使用WCF服務，我遇到了同樣的問題（空配置客戶端），並且我無法創建客戶端服務引用的實例。 以下方式適用於我：

1-右鍵單擊ServiceRefernce文件夾下的引用服務。 2-在菜單中選擇配置服務參考以訪問服務參考設置。 3-在裝配清單上方，選擇「指定的引用裝配中的重新使用類型：」。 4-檢查列表「System.ServiceModel」並按確定。

我希望這會有所幫助。
