The basic of MVVM is an implementation of the INotifyPropertyChanged interface. All View Models must implement it, and the entire binding mechanism between the views and the view models rely on it.

Overview
In my previous post, “Friendly UI Development process”, I introduced a UI application architecture that allows for a more “friendly” development process.
