配置WCF端点？聊天服务器和客户端

Question

我想配置我的客户端程序和我的聊天服务器程序的WCF端点。

当我到那里的逻辑尝试连接（客户端登录到服务器）的时候，我得到以下错误：

Could not find endpoint element with name 'ChattingServiceEndpoint' and contract 'ChattingInterfaces.IChattingService' in the ServiceModel client configuration section. This might be because no configuration file was found for your application, or because no endpoint element matching this name could be found in the client element.

这当我试图打开在一个DuplexChannelFactory显然发生在我的WPF聊天客户端聊天窗口的后面代码：

_channelFactory = new DuplexChannelFactory<IChattingService>(new ClientCallback(), "ChattingServiceEndpoint"); 

我看到在客户端和服务器的配置文件，为“ChattingServiceEndpoint”的WCF配置。那么真正缺少的是什么？我把serviceModel标签放在了app.config文件的错误部分吗？我是否需要将它包含在我用来将客户端连接到服务器的ChattingInterfaces库的app.config中？

这里是客户端和服务器的app.config文件。

我愿意发布更多代码文件在必要时帮助诊断这一问题。任何人都知道该怎么做/发生了什么？谢谢！

我又做了。

我发布了我将归类为“poofus问题”的内容。原来，配置文件中的端点名称和其他数据区分大小写。确保端点完全匹配，在大小写字符中一字不差！
