在 DevExpress Code Central 数据库中可以找到完整的示例项目，网址是 http://www.devexpress.com/example=E2876。 取决于目标平台类型 (ASP.NET、WinForms 等)，可以在线运行本示例，或者下载自动可执行的示例。

此示例展示了如何使用 ServiceReferences.ClientConfig 文件来配置 ReportService(报表服务) 的客户端选项。

在下面显示了 ServiceReferences.ClientConfig 文件的内容。

<configuration>
    <system.serviceModel>
      <bindings>
        <basicHttpBinding>
          <binding name="basicBindingConfiguration"
                   closeTimeout="00:33:00"
                   openTimeout="00:33:00"
                   sendTimeout="00:33:00"
                   receiveTimeout="00:33:00"/>
        </basicHttpBinding>
      </bindings>
      <client>
        <endpoint name="endpointConfiguration"
                  address="../ReportService1.svc"
                  binding="basicHttpBinding"
                  bindingConfiguration="basicBindingConfiguration"
                  contract="ServiceReference.IReportService" />
      </client>
    </system.serviceModel>
</configuration>

注意，不能把 ReportPreviewModel.ServiceUri 属性设置为空字符串，因此应该在 XAML 中始终至少指派一个代用值。
