This class encapsulates a Culture and a keyboard LayoutName, which determine how input is handled in the current thread or process.

There are static members, which allow you to retrieve the CurrentInputLanguage and the DefaultInputLanguage, as well as a list of all the InstalledInputLanguages on a system.

You could use this class to provide custom input handling for different environments, perhaps modifying the Control.RightToLeft status or changing the IME (see ImeMode).
