使用雙工通道的未處理通信異常

Question

我正在使用WCF雙工通道進行服務回調交互，另外我在另一個端口上使用另一個服務。經過一段時間後，雙工通道出現故障，但是當我嘗試使用它時，我收到通信異常（我不知道通道何時發生故障，我無法使用SessionFaulted事件）。接收超時是無限的，setTimeout是30秒。

問題是我找不到處理此異常的方法，沒有堆棧跟蹤，我無法在任何地方捕獲它。

我用診斷/錯誤處理行爲擴展來調查，但沒有運氣。

例外：

2013-12-23 11:00:34,514 ERROR General - An exception was thrown during a service call. 
Details: System.ServiceModel.CommunicationException: The socket connection was aborted. 
This could be caused by an error processing your message or a receive timeout being exceeded by the remote host, or an underlying network resource issue.

    at System.ServiceModel.Dispatcher.DuplexChannelBinder.EndTryReceive(IAsyncResult result, RequestContext& requestContext)

任何想法？

Answer 1

經過長時間的研究以及我沒有其他選擇後，我決定比較舊回調和新回調的引用，如果它們不同，則替換舊回調。

對方接到故障後將關閉它的一側。

這不是最好的解決方案，因爲它有點剎車通信合同，但它做的工作。
