【问题描述】:
我正在使用 WCF(使用回调协定)和 netTcpBinding 创建一个聊天应用程序。 我将该服务托管为 Windows 服务并从其他计算机访问它 通过客户端应用程序。
我现在面临的问题是客户端连接在之后进入故障状态 10 分钟,这似乎是某种超时发生。 我已经尝试在服务和客户端中增加接收超时和发送超时,但没有奏效。
我应该更改哪个设置以增加此超时时间以及在哪个应用程序、服务或客户端中?
以下是我的配置文件,

【问题讨论】:

您是否尝试过将 receiveTimeout 设置为 -1。 msdn.microsoft.com/en-us/library/ms824661.aspx。称为无穷

感谢 Shoaib,我尝试使用无限但不接受配置文件中的有效值。有什么理由吗?无论如何,我做了一个小解决方法,以便该服务每 5 分钟刷新一次每个客户端。但我想应该有办法通过配置来处理这个问题。
