Application Framework Component

MyCS application framework component implements core foundational classes that provides framework for building:

• application features
• managing state and data services
• handling of notifications

The Feature framework

The following sequence diagram outlines the life-cycle of a feature.

            Note right of Feature: This is an implementation<br/>of the Feature class and it<br/>implements the feature's<br/> scope, state and anchors<br/>for UI hooks.
