Question

使用WCF Net TCP，一天内会出现几个错误。

当客户端向服务器发送消息时发生。

ERROR：System.Net.Sockets.SocketException: An existing connection was forcibly closed by the remote host
System.ServiceModel.Channels.SocketConnection.Write(...)

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.

Answer 1

我认为system.serviceModel下的protocolMapping标签存在一些问题。希望它有用：）
