The Application Configuration File

The application configuration file is the one configuration file that you have complete control over, and it is where you should put your application configuration settings. The application configuration file is automatically read when necessary, and it must be located in the same directory as the application, and named with the same name as the application executable plus the extension .config. If your application executable is named C:\MyApp.exe, for example, the application configuration file must be named C:\MyApp.exe.config.

In the next section, I’ll describe how you can add your own settings to the machine or application configuration files.
