Provides a string that describes an application settings property group. This class cannot be inherited.
An application settings class, derived from System.Configuration.ApplicationSettingsBase, defines one or more properties that belong to the same application property group. System.Configuration.SettingsGroupDescriptionAttribute is an optional attribute that you can use to provide descriptive text for a settings property group. This text is intended to assist both design-time tools and administrative run-time tools in identifying and describing the associated property group.
This attribute can only be applied at the wrapper class level.
