In Chapter 14, I introduce the new configuration management API of ASP.NET 2.0 that enables users to
programmatically build programs or scripts that create, read, and update settings in web.config and
machine.config files. I also go on to discuss the new comprehensive admin tool that plugs into the exist-
ing IIS Administration MMC, enabling an administrator to graphically read or change any setting within
our XML configuration files. Throughout this chapter, I focus on the new configuration management
classes, properties, and methods of the configuration API and also provide examples on how to use
them from your ASP.NET applications.
