Introduction to WPF

• Microsoft based UI framework
• Graphical subsystem for rendering user interfaces
  in Winforms.
• WPF, previously known as "Avalon"
• 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.

Advantages of WPF

• Effective use of Graphics card. Highly suitable
  for high end /upcoming computers
• Built in Animation controls
• Supports most of the media/document formats
  natively
• XAML(Designer and developer can work
  independently)
• Silverlight (WPF/e)

7
Disadvantages of WPF

• WPF will not run on windows 2000 or lower.
• It is Missing some controls which are available
  Windows Forms
• e.g. - DataGridView and PropertyGrid
• Very little help documents
• Very designer orientated

WPF VS WinForms Development

• WPF provides an uniform platform to use video,
  speech, text, 2D and 3D graphics.
• WPF applications can take advantage of Graphics
  Processing Units on Graphics cards for smoother
  graphics
• WPF is steep learning curve
• Winforms have lots of controls and lots of help
  available

9
WPF VS WinForms Development(Continued)

• WPF allows separation of design work by Designers
  and functionality by WPF Developers
• Better GUI and smart cleint

10
Design Option - Screen
Window Form
Windows Presentation Foundation

Future of WinForm Development

• Experts say that Microsoft for Windows Forms
  beyond Version 2.0 released in 2005)
• So it might force the business to migrate their
  current WinForm applications to WPF and start new
  applications on WPF

12
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
• WPF requires.NET Framework Version 3.0 which is a
  free download from Microsoft Web site.
• .NET Framework 3.0 is shipped with Windows Vista.
  No install hassle.

When to use WPF

• New applications
• To build rich and highly interactive application
  that is sophisticated
• Highly Custom branded
• Apply enhanced user experience
• Existing application
• If you have an existing app that is just form
  based, you must just want to keep that in windows
  forms
• No clean separation on logic and view Then WPF
  is the way

15
Conclusions

• Silverlight light and WPF shares same development
  tools and models
• However, WPF but is optimized for a lightweight,
  cross-platform runtime
• Investing in either WPF development or
  Silverlight development meshes your skills,
  tools, and assets for these platforms
