c# - 使用 TCP : "The message could not be dispatched..." 时收到错误

Question

我不熟悉创建 WCF 服务。我在 VS2008 中创建了一个运行在 IIS 7 上的 WCF Web 服务。当我使用 http 时，该服务运行良好。当我为 TCP 配置服务并运行时，我收到以下错误消息。

There was a communication problem. The message could not be dispatched because the service at the endpoint address 'net:tcp://elec:9090/CoordinateIdTool_Tcp/IdToolService.svc is unavailable for the protocol of the address.

我搜索了很多论坛，包括这个论坛，寻找解决方案，但没有任何效果。 IIS 7 上的一切似乎都已正确设置。WAS 已设置为运行。默认网站有一个 net.tcp 绑定(bind)，应用程序在启用的协议(protocol)下有 net.tcp。

我包括了我认为是主机项目的 web.config 的重要部分以及我用来测试服务的客户端项目的 app.config。希望有人能发现我的错误。提前感谢任何人可以提供的任何帮助或建议。

我想我的问题和你的类似。我做了什么，我去了 WCF 网络服务的站点，而不是应用程序池，进入高级设置，从启用的协议(protocol)中删除了 net.tcp，点击确定，保存了设置，称为 net.tcp 服务，它当然给了我股票异常(exception)...

 Could not find a base address that matches scheme net.tcp for the endpoint with binding NetTcpBinding. Registered base address schemes are [http]. 

然后我将 net.tcp 重新添加到启用的协议(protocol)中。然后网络服务运行得非常好。我不确定为什么会这样。我认为它强制重置了 TCP 监听器。不过我不能确定。
