服務器端WCF（.svc）服務在異常後停止工作

Question

我在WCF中使用雙工ReliableSecureProfile，如果任何客戶端發生異常，服務器將停止監聽新請求。

如何讓服務器對任何單個客戶端發生的故障具有更強的恢復能力？一切再次工作，如果我重新啓動服務器或重新部署

我的客戶端代碼如下所示：

  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文件看起來是這樣的：

<system.serviceModel> 

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

Answer 1

我不能重現此問題了（服務器只停止響應）。我覺得這裏解釋的問題是關係到VS2010的願望捕捉處理的異常，並停止所有線程：
