服务器端WCF（.svc）服务在异常后停止工作

问题描述：

我在WCF中使用双工ReliableSecureProfile，如果任何客户端发生异常，服务器将停止监听新请求。服务器端WCF（.svc）服务在异常后停止工作

如何让服务器对任何单个客户端发生的故障具有更强的恢复能力？一切再次工作，如果我重新启动服务器或重新部署

我的客户端代码如下所示：

  CustomBinding rspBinding = new CustomBinding(); 
      rspBinding.Elements.Add(new ReliableSessionBindingElement()); 
      rspBinding.Elements.Add(new MakeConnectionBindingElement()); 
      rspBinding.Elements.Add(new TextMessageEncodingBindingElement()); 
      rspBinding.Elements.Add(new HttpTransportBindingElement()); 

      DuplexChannelFactory<IProcessDataDuplex> channelFactory = 
       new DuplexChannelFactory<IProcessDataDuplex> 
        (new CallbackHandler(), rspBinding, serviceAddress); 

      // 
      // The problem always occurs on this line. 
      // 
      reusableSW = new LC.Utils.WCF.ServiceWrapper<IProcessDataDuplex>(channelFactory);

我的web.config文件看起来是这样的：

<system.serviceModel> 

    <behaviors> 
     <serviceBehaviors> 
     <behavior name="rspServiceBehavior"> 
      <serviceMetadata httpGetEnabled="true" policyVersion="Policy15" />

什么是你的客户做的异常后的通道已经被抛出？它是否正确清理？ – razlebe 2011-05-31 00:38:51

@razlebe - 不，它没有正确清理。我试图说服那个服务器端。这是一个被滥用的公共服务 – LamonteCristo 2011-05-31 00:45:17

答

我不能重现此问题了（服务器只停止响应）。我觉得这里解释的问题是关系到VS2010的愿望捕捉处理的异常，并停止所有线程：
