我正在使用WCF在C#中编写客户端/服务器应用程序.我的所有测试都没问题,但是一旦我部署了服务,我发现与服务器通信时出现了随机问题.我启用了调试并在服务器中看到了这样的消息:
The communication object, System.ServiceModel.Channels.ServerReliableDuplexSessionChannel, cannot be used for communication because it has been Aborted.

模式是这样的:
应用程序如下所示:服务实例提供了与数据库交互的API方法,其类型为"netTcpBinding".几个客户端(大约40个)连接并从服务中随机调用方法.即使没有发送或接收任何东西,客户也可以保持开放几天.
