4 What’s Windows Presentation Foundation?

The Windows Presentation Foundation is Microsoft’s next generation UI framework to create applications with a rich user experience. It is part of the .NET framework 3.0 and higher. WPF combines application UIs, 2D graphics, 3D graphics, documents and multimedia into one single framework. Its vector based rendering engine uses hardware acceleration of modern graphic cards. This makes the UI faster, scalable and resolution independent. What’s Windows Presentation Foundation?

Next generation presentation subsystem for Windows Unified programming model Harness the power of new graphics hardware Provide designers direct input into project development Enables developers and designers to create visually stunning user interfaces What’s Windows Presentation Foundation?

WPF: Using the Hardware Vector-based composition engine uses the PC’s graphics power Quality is preserved with scale CPU freed from graphics work Gain capability from graphics card advances

5 What type of Applications can be built

WPF intended to replace both webforms and windows forms – apps can be built to run in a browser or a standalone window Windows forms and WPF pages/windows can co-exist in the same application One WPF page/window can have both types of controls on it A new type of web application called XAML Browser Application XBAP (formerly Web Browser Application WBA) What type of Applications can be built

What do the applications look like WPF intended to replace both webforms and windows forms – apps can be built to run in a browser or a standalone window Windows forms and WPF pages/windows can co-exist in the same application One WPF page/window can have both types of controls on it A new type of web application called XAML Browser Application XBAP (formerly Web Browser Application WBA)

6 Why use WPF?

WPF is an especially great platform to use if your applications involve various media types.If you need to incorporate video, or documents, 3D content and animated transitions between a sequence of images, or a combination of any of the above.  WPF is also great if you need to create a skinned user interface, or if you need to bind to XML data, or dynamically load portions of a user interface from a Web service, or want to create a desktop application with a Web-like navigation style. Why use WPF?

7 How can I make it to do that?

XAML = Extensible Application Markup Language Easily toolable, declarative markup Code and content are separate Can be rendered in the browser / standalone application How can I make it do that?

8 Advantages of WPF?

The ability to make very rich UIs relatively easily. Easier animation and special effects Inherent scalability  WPF builds on DirectX rather than WinAPI, harnessing the power of the client computer's graphics system thus giving much greater graphic rendering power WPF uses a vector graphics system which means UIs are completely re-sizeable without loss of quality WPF supports flow document model that gives a 'desktop publishing' quality of layout  Supports ‘rich data visualisation’ Advantages of WPF?

9 Disadvantages of WPF?

WPF will not run on windows 2000 or lower. WPF's in-box control suite is far more limited than that of WinForms. Disadvantages of WPF?
