This class provides a variety of static methods to start message processing for a Windows Forms application, and to retrieve information about the execution environment of the current application, including such useful details as the shared and user data paths, registry keys, locale/culture settings, and others.

You can also get notifications of and some control over application startup and shutdown, although the exit notification is not signaled if you use the parameterless version of Run().

Finally, there is a facility to install and remove message filters for your application with AddMessageFilter() and RemoveMessageFilter(). See IMessageFilter for information on this feature.
