1. Purpose

RibbonViewModel<TModel> is a generic base class for ribbon control view models in a WPF/Prism application. It provides common infrastructure for ribbon-based UI components including command management, lifecycle methods (initialization, activation, cleanup), status publishing via event aggregation, and property change notification. This class serves as a foundation for specific ribbon view model implementations that manage a model of type TModel.
