Take a loot at following fragments:
public class BindableBase : INotifyPropertyChanged
public event PropertyChangedEventHandler PropertyChanged;
public void RaisePropertyChanged(string propertyName)
if(PropertyChanged != null)
PropertyChanged.Invoke(this, new PropertyChangedEventArgs(propertyName));
Class BindableBase now can become as base class for those objects, which need to notify UI about changes in source code. Consider … more

today I want to write few words about basic elements in XAML.
This class is next in inheritance level in XAML after object. DependencyObject gives needed properties for representing something that participates in dependency property system. Mostly needed for data binding. It is basic for UIElement, Geometry, FameworkTemplates, Tile, ResourceDictionary.
This is base class for all objects that have visual representation. It supports basic manipulation, appereance, layout. Also it has code for responses for user input, routed events, some aspects of animation system.
This class takes part in layout and obliged to have … more
