WCF and Windows Store apps, ConfigurationErrorsException

当我尝试创建服务的新实例时，我得到一个"ConfigurationErrorsException"。

编辑:我的应用程序和WCF服务不在同一台机器上。Wcf服务在Windows Server 2012上运行

我在Windows Store应用程序中的代码是这样的:

 var api = new ServiceRef.MyTestServiceClient(ApiServiceClient.EndpointConfiguration.BasicHttpEndpoint);

我的WCF配置是(它作为windows服务托管):

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <system.serviceModel>
    <services>
      <service name="MyTestService.MyTestService"
               behaviorConfiguration="MyTestServiceBehavior">
        <host>
          <baseAddresses>
            <add baseAddress="http://localhost:8000/"/>
          </baseAddresses>
        </host>
        <endpoint address="" binding="basicHttpBinding"
          name="BasicHttpEndpoint"
          bindingConfiguration=""
          contract="MyTestService.IMyTestService">
          <identity>
            <dns value="localhost" />
          </identity>
        </endpoint>
        <endpoint address="mex" binding="mexHttpBinding"
           contract="IMetadataExchange" />
      </service>
    </services>
    <behaviors>
      <serviceBehaviors>
        <behavior name="MyTestServiceBehavior">
          <serviceMetadata httpGetEnabled="true"/>
          <serviceDebug includeExceptionDetailInFaults="False"/>
        </behavior>
      </serviceBehaviors>
    </behaviors>
  </system.serviceModel>
</configuration>

完整的错误信息是:
