The Windows Presentation Foundation, formerly code-named Avalon, is the graphical subsystem feature of the .NET Framework 3.0 and is directly related to XAML. It provides a consistent programming model for building applications and provides a clear separation between the UI and the business logic.
A WPF application can be deployed on the desktop or hosted in a web browser. It also enables rich control, design, and development of the visual aspects of Windows programs. It aims to unify a host of application services: user interface, 2D and 3D drawing, fixed and adaptive documents, advanced typography, vector graphics, raster graphics, animation, data binding, audio and video.

The architecture of Windows Presentation Foundation spans across both managed code and native code components; however, the public API exposed is only available via managed code. While the majority of WPF is in managed code, the composition engine which renders the WPF applications is a native component.
The Windows Presentation Foundation interfaces directly with DirectX and provides basic support for 2D and 3D surfaces, timer-controlled manipulation of contents of a surface with a view to exposing animation constructs at a higher level, and compositing the individual elements of a WPF application into a final 3D "scene" that represents the UI of the application and renders it to the screen.

The Windows Presentation Foundation exposes a property system for objects which inherit from DependencyObject that is aware of the dependencies between the consumers of the property, and can trigger actions based on changes in properties. Properties can be either hard coded values or expressions, which are specific expressions that evaluate to a result.
In the initial release, however, the set of expressions supported is closed. The value of the properties can be inherited from parent objects as well. WPF properties support change notifications, which invoke bound behaviors whenever some property of some element is changed. Custom behaviors can be used to propagate a property change notification across a set of WPF objects. For more information about the Windows Presentation Foundation, then visit the
