What is WPF – Windows Presentation Foundation.

Windows Presentation Foundation (WPF) is the answer for software developers and graphic designers who want to create modern user experiences without having to master several difficult technologies.  WPF aims to combine the best attributes of systems such as DirectX (3D and hardware acceleration), Windows Forms (developer productivity), Adobe Flash (powerful animation support), and HTML (declarative markup and easy deployment).  WPF is a major component of the .NET Framework, starting with version 3.0. (This is why the first version of WPF carries a 3.0 version number rather than 1.0!)
