.net - 配置 WCF 客户端出现错误“无法处理消息。这很可能是因为操作

Question

无论我设置什么配置，我的网络服务都会返回一条错误消息。我收到以下错误消息。

The message could not be processed. This is most likely because the action 'http://tempuri.org/ITestingWebService/DoWork' is incorrect or because the message contains an invalid or expired security context token or because there is a mismatch between bindings. The security context token would be invalid if the service aborted the channel due to inactivity. To prevent the service from aborting idle sessions prematurely increase the Receive timeout on the service endpoint's binding.

这是我的 WCF 服务器和客户端 web.config 部分。

您很可能在 ITestingWebService 接口(interface)上有不匹配的服务契约(Contract)。尝试通过右键单击 Visual Studio 中的服务引用来运行“更新服务引用”，看看是否可以解决问题。
