    • W indows P resentation F oundation Next-Generation User Experiences.
    • Introduction to WPF
      • It is a graphical subsystem for rendering user interfaces in Winforms.
      • WPF, previously known as "Avalon", was initially released as part of .NET Framework 3.0.
      • WPF is essentially an alternative method for developing Windows based applications.
    • Introduction to WPF (Continued)
      • Designed to remove dependencies on the aging Graphics Device Interface(GDI) subsystem, WPF is built on DirectX, which provides hardware acceleration and enables modern UI features. e.g.:- Transparency, Gradients and Transforms.
    • Introduction to WPF (Continued)
      • WPF provides a consistent programming model for building applications and provides a clear separation between the user interface and the business logic.
    • Technology growth Windows API MFC Microsoft Foundation Class Library Windows Forms Windows Presentation Foundation
    • Advantages of WPF
      • Effective use of Graphics card. Highly suitable for high end /upcoming computers.
      • Built in Animation.
      • Supports most of the media/document formats natively.
      • XAML(Designer and developer can work independently).
      • Silverlight (WPF/e)

    • Disadvantages of WPF
      • WPF will not run on windows 2000 or lower.
      • At the present time there are certain controls available in Windows Forms for which no WPF equivalent exists
      • e.g. :- DataGridView and PropertyGrid
    • WPF and Silverlight
      • Silverlight (formerly known as WPF/e—the "e" stands for "everywhere") is a restricted version of WPF designed to run securely in a browser while still providing a rich user interface. Because of the security restrictions, Silverlight does not provide all the features included in WPF. Some features are missing while others are provided in a restricted way.
      • Currently only in beta form, Silverlight supports Firefox and Internet Explorer 7 on Windows and Firefox and Safari on the MAC.
    • WPF VS WinForms Development
      • WPF has a number of advantages over Windows Forms development which include
      • Comprehensive Integration – WPF provides a uniform platform for using video, speech, text, 2D and 3D graphics.
      • WPF applications can take advantage of G raphics P rocessing U nits on Graphics cards for smoother graphics.
    • WPF VS WinForms Development (Continued)
      • WPF allows separation of design work by Designers and functionality by Developers.
      • Better GUI
    • Window Form
    • The Future of WinForm Development
      • One of the authors of a leading WPF book, has suggested that there will be no further development by Microsoft for Windows Forms beyond Version 2.0 (released in 2005).
    • WPF and Windows OS
      • WPF does not explicitly require Windows Vista.
      • WPF also will work with Windows XP Service Pack 2 and with Windows Server 2003 SP1
      • IT require the .NET Framework Version 3.0, a free download from Microsoft Web site.
      • .NET Framework 3.0 Comes with Windows Vista. So no need to install.
    • Developer & Designer with WPF
    • Working with WPF
      • XAML code is principally the textual representation of some visual element – either a graphic object or a user interface object such as a button or a combo box.
      • Easy for tools to consume and generate.
      • It is new to Developers.
      • Under the standard paradigm the User Interface is described in XAML and the underlying functionality is built using C# (or Visual Basic.NET).
    • Working with WPF (Continued) <Button Width=&quot;60&quot;> OK <Button.Background> Blue </Button.Background> </Button> Button btn=new Button(); btn.Content=&quot;OK&quot;; btn.Width=60; btn.Background=new SolidColorBrush(Colors.Blue); Dim btn As New Button btn.Content=&quot;OK&quot; btn.Width=60 btn.Background=new _SolidColorBrush _(Colors.Blue) OK
    • Conclusions
      • If you have an existing Windows Forms application or are building a traditional forms-based application and are looking for a mature technology to use with mature tools and component support then Windows Forms is a good fit.
      • If you’re wanting to create a new experience for your users that is rich, interactive, sophisticated, or highly custom or branded, WPF is Microsoft’s next-generation platform for your project today.
    • Conclusions
      • If you’re targeting the web, Silverlight shares the same development model as WPF but is optimized for a lightweight, cross-platform runtime. Investing in either WPF or Silverlight nets you the skills, tools, and assets for both platforms.
