Question

我在使用.Net 4.0路由服务连接到使用回调的服务时遇到问题。据我所知，路由服务支持绑定和回调。仅服务和客户端运营良好。

我做了什么，是在这里找到MS WCF和WF样本：http://www.microsoft.com/downloads/en/details.aspx?FamilyID=35ec8682-d5fd-4bc3-a51a-d8ad115a8792&displaylang=en

并更改配置以匹配我的服务绑定。我可以通过路由服务从客户端调用操作到服务，客户端不会收到从服务到客户端的回调。

使用控制台应用程序作为主机

，配置路由服务如下

using (ServiceHost serviceHost =
            new ServiceHost(typeof(RoutingService)))
        {
            serviceHost.Open();
            Console.ReadLine();
        }

<system.serviceModel>
<diagnostics>
  <messageLogging logMalformedMessages="true" logMessagesAtServiceLevel="true"
    logMessagesAtTransportLevel="true" />
</diagnostics>
<services>
  <!--ROUTING SERVICE -->
  <service behaviorConfiguration="routingData" name="System.ServiceModel.Routing.RoutingService" >
    <host>
      <baseAddresses>
        <add  baseAddress="http://localhost:8000/routingservice/router"/>
      </baseAddresses>
    </host>
    <endpoint address=""
              binding="wsDualHttpBinding"
              name="reqReplyEndpoint"
              contract="System.ServiceModel.Routing.IRequestReplyRouter"
              bindingConfiguration="UnSecureBinding"/>
    <endpoint address="mex"
              binding="mexHttpBinding"
              contract="IMetadataExchange"  />
  </service>
</services>
<behaviors>
  <serviceBehaviors>
    <behavior name="routingData">
      <serviceMetadata httpGetEnabled="True"/>
      <serviceDebug includeExceptionDetailInFaults="true" />
      <routing filterTableName="routingTable1" />
    </behavior>
  </serviceBehaviors>
</behaviors>
<bindings>
  <wsDualHttpBinding>
    <binding name="UnSecureBinding">
      <security mode="None" />
    </binding>
  </wsDualHttpBinding>
</bindings>
<client>
  <endpoint name="NotificationService"
            address="http://localhost/CommServices/NotificationService.svc"
            binding="wsDualHttpBinding"
            bindingConfiguration="UnSecureBinding"
            contract="*" />
</client>
<!--ROUTING SECTION -->
<routing>
  <filters>
    <filter name="MatchAllFilter1" filterType="MatchAll" />
  </filters>
  <filterTables>
    <filterTable name="routingTable1">
        <add filterName="MatchAllFilter1" endpointName="NotificationService" />
    </filterTable>
  </filterTables>

如果我启用ServiceModel跟踪，我可以在WCF堆栈深处看到一个ArgumentException，到目前为止跟踪了一条跟踪。

任何人都可以提示正确的方向，或者纠正我如果我对RoutingService的回调功能的假设是错误的。

如果有人像我一样绊倒，问题是路由器端点上的合同。 RequestReplyRouter不支持回调，但IDuplexSessionRouter支持回调。

<endpoint address=""
              binding="wsDualHttpBinding"
              name="reqReplyEndpoint"
              contract="System.ServiceModel.Routing.IDuplexSessionRouter"
              bindingConfiguration="UnSecureBinding"/>

此致多米尼克

WCF RoutingService没有使用回调路由wsDualHttpBinding
