wsDualHttpBinding在Azure下部署时不工作

Question

WCF双工不在Azure下工作。在IIS下一切正常工作。我知道双工绑定是有问题的，因为服务器回调，但是.我已经关闭了防火墙。TCPView (Sysinternals)显示客户端发送/接收10到12个数据包，然后它就死了.什么都没发生。我把所有的超时时间都设置为10分钟。

下面请看我的配置文件。

服务器配置：

  <system.serviceModel>
<services>
  <service behaviorConfiguration="MexBehaviour" name="MySrvc">
    <endpoint address="" binding="wsDualHttpBinding" bindingConfiguration="wsDualHttpBinding"
      name="wsDualEndpoint" bindingName="wsDualHttpBinding" contract="IMySrvc" />
    <endpoint address="mex" binding="mexHttpBinding" bindingConfiguration="mexHttpBinding"
      name="MexEndpoint" bindingName="mexHttpBinding" contract="IMetadataExchange" />
    <host>
      <baseAddresses>
        <add baseAddress="http://srvc.azurewebsites.net/MySrvc.svc" />
      </baseAddresses>
      <timeouts openTimeout="00:10:00" />
    </host>
  </service>
</services>
<bindings>
  <wsDualHttpBinding>
    <binding name="wsDualHttpBinding" openTimeout="00:10:00" sendTimeout="00:10:00"
      clientBaseAddress="http://xxx.xxx.xxx.xxx:xxx">
      <security mode="None">
        <message clientCredentialType="None" negotiateServiceCredential="false" />
      </security>
    </binding>
  </wsDualHttpBinding>
  <mexHttpBinding>
    <binding name="mexHttpBinding" />
  </mexHttpBinding>
</bindings>
<behaviors>
  <serviceBehaviors>
    <behavior name="MexBehaviour">
      <serviceMetadata httpGetEnabled="true" httpsGetEnabled="true" />
      <serviceDebug includeExceptionDetailInFaults="false" />
    </behavior>
  </serviceBehaviors>
</behaviors>
<protocolMapping>
    <add binding="basicHttpsBinding" scheme="https" />
</protocolMapping>    
<serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true" />

客户端配置：

    <system.serviceModel>
    <bindings>
        <wsDualHttpBinding>
            <binding name="wsDualEndpoint">
                <security mode="None" />
            </binding>
        </wsDualHttpBinding>
    </bindings>
    <client>
        <endpoint address="http://srvc.azurewebsites.net/MySrvc.svc"
            binding="wsDualHttpBinding" bindingConfiguration="wsDualEndpoint"
            contract="SrvcRef.IMySrvc" name="wsDualEndpoint" />
    </client>
</system.serviceModel>

我知道这个wsDualHttpBinding没有通过“嗅觉测试”.来自Juval Lowy的书“编程WCF服务:掌握WCF和Azure AppFabric服务总线”：

WSDualHttpBinding大多是不可用的，因为实际上不可能穿越将服务与客户端分离开来的各种通信障碍，并且需要找到特定的web服务器机器，这使得这种做法不切实际。

我用netTcpBinding来解决我的问题.您只需要让IIS使用TCP协议即可。有很多文章解释如何做这件事。这里有一个：http://msdn.microsoft.com/en-us/library/ms731053.aspx

干杯。
