Configuring endpoint by editing xml web.config is not friend. In fact there is a GUI that the developers can be used to configure the service endpoint, WCF Service Configuration Editor. I still do not see the how-to article for this tool in msdn web site.
To open this tool:
1. Start Visual Studio 2008.
2. Choose Tools -> WCF Service Configuration Editor
Open the web.config in your WCF Service Configuration Editor.
