访问net.tcp WCF操作合同时出错

Question

我有简单的WCF服务，我成功地在IIS 7下托管它。我也可以生成客户端（使用WCFTestClient.exe util），但是当我尝试运行Wcf方法时，我收到以下错误

  

无法调用该服务。可能的原因：服务离线或无法访问;客户端配置与代理不匹配;现有代理无效。有关更多详细信息，请参阅堆栈跟踪。您可以尝试通过启动新代理，还原到默认配置或刷新服务来恢复

我的服务是获取输入并以“您输入的内容：{0}”格式返回字符串。 这是我的web.config

<system.serviceModel>
<services>
  <service behaviorConfiguration="ServiceBehavior" name="II7WcfService.MyService">

    <host>
      <baseAddresses>
        <add baseAddress="net.tcp://localhost/artur/MyService" />
      </baseAddresses>
    </host>
