在 WP7 应用中引用 WCF 时为空配置文件

Question

我正在尝试从WP7应用程序使用自己的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">
          <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>
        </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>

当我在控制台客户端中引用 WCF 服务时，客户端配置文件如下所示：

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

问题是当我尝试从 WP7 项目中使用 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...和 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

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

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

Answer 1

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 basicHttpBinding ，这是 silverlight 项目支持的唯一绑定。:(

KeyNotFoundException是由于默认绑定 （ BasicHttpBinding ） 在服务的绑定列表中不存在（仅在服务中找到WSHttpBinding）。

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

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

尽管此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法。

我遇到了同样的问题。我所做的是：
1.右键单击服务引用。
阿拉伯数字。选择"配置服务引用..."
3.无需更改出现的对话框中的任何内容。
4.单击对话框中的"确定"。

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

希望这会有所帮助。

Answer 3

> 为了在 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），并且无法创建客户端服务引用的实例。以下内容对我有用：

1-右键单击文件夹下引用的服务。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-签入列表"系统.服务模型"，然后按确定。

我希望这会有所帮助。
