* Dependency properties are used to enable styling, automatic data binding, templates, animation etc.
* All types that want to use DependencyProperties must derive from 'DependencyObject' class.
* The value of a DependencyProperty is resolved dynamically when read.
* The value of a dependency property is stored in a dictionary of keys and values provided by 'DependencyObject' class.
* Advantages:
1) Reduced memory footprint
2) Value Inheritance
3) Change Notification
