How are configuration files used in VB .NET?
You can use configuration files to configure .NET applications without compiling them. These configuration files help you to store application variables and configuration values, just as you could with earlier versions of Visual Basic (by using .ini files and later, registry settings). In addition, Visual Basic .NET configuration files allow you to keep properties for visual components so they can be dynamically changed by just editing a text file. Configuration files can contain different types of information, depending on the type of application that will use them. A configuration file for a .NET client application will be significantly different from those for a .NET server application: the configuration file will contain different sections, attributes, and values.
