我正在尝试从 WP7 应用程序使用我自己的 WCF 服务。

WCF 服务中的配置文件

<?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">

        </endpoint>

        <endpoint address="" binding="wsHttpBinding" contract="mergedServices.keywordSearchServiceInterface">

          </identity>
        </endpoint>

        <endpoint address="" binding="wsHttpBinding" contract="mergedServices.QAServiceInterface">
          <identity>

            <add baseAddress="http://localhost:8732/Design_Time_Addresses/mergedServices/" />
          </baseAddresses>
        </host>
      </service>

    </services>

          <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>

问题是当我尝试使用 WP7 项目中的 WCF 服务时，当我引用该服务时，这是配置文件中的内容：

<configuration />

就是这样............当我启动应用程序时，出现以下运行时错误：

System.Collections.Generic.KeyNotFoundException was unhandled
  Message=KeyNotFoundException
  StackTrace:
       at System.ThrowHelper.ThrowKeyNotFoundException()

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

绑定后引用应该返回配置文件，我不确定出了什么问题，我没有在 IIS 上托管 WCF，我只是在试用 WP7 应用程序期间在后台运行 WCF 库的项目模拟器。

windows phone 7 的运行时间是 silverlight，不支持WSHttpBinding. 您必须将服务绑定更改为basicHttpBindingSilverlight 项目支持的唯一绑定。:(

这KeyNotFoundException是由于默认绑定 ( BasicHttpBinding) 不存在于服务的绑定列表中（仅WSHttpBinding在您的服务中找到）。

如果您不能或不想接触原始WSHttpBinding配置的 WCF 服务，您仍然可以通过利用适配器设计模式来解决它。

当我开发使用WSHttpBindingWCF 服务的 Windows Phone 应用程序时，我遇到了这个确切的问题。最后，我必须实现一个适配器WCF 服务，该服务本身已BasicHttpBinding配置并使用原始WSHttpBinding服务。然后让 Windows Phone 应用程序改为使用适配器服务。

尽管这种适配器方法需要一些额外的工作，但它仍然是一种优雅的解决方案。

我遇到了同样的问题。我所做的是：
1. 右键单击​​服务参考。
2. 选择“配置服务参考...”
3. 无需更改出现的对话框中的任何内容。
4. 在对话框中单击“确定”。

这为我重新生成了“ServiceReferences.ClientConfig”文件。

希望这会有所帮助。

要在 vs2013 上使用 windows phone 8 项目中的 WCF 服务，我遇到了同样的问题（空配置客户端），我无法创建客户端服务引用的实例。以下对我有用：

1- 右键单击​​文件夹 ServiceReference 下的引用服务。2- 在菜单中选择配置服务参考以访问服务参考设置。3- 在程序集列表上方，选择“在指定的引用程序集中重用类型： ”。4- 检查列表“ System.ServiceModel ”，然后按OK。

我希望这将有所帮助。
