WCF采用 netTcpBinding 发生的Socket errors

最近在项目中采用 Windows service 作为WCF services的宿主, 在服务和客户端的调用上没有发生如何的异常和错误,但是经常发生下述错误：

“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. Local socket timeout was '10675199.02:48:05.4775807'”

下面是一个解决方案：当使用WCF 服务使用 netTcpBinding 时，需要在客户端代理调用方法close()关闭代理，将服务的实例放回到池中。
