2.  What is WPF ?
 Types Of WPF Applications.
 WPF Assemblies.
 XAML ( free And Centric WPF applications ).

3.  Over the years, Microsoft has developed numerous
graphical user interface toolkits (raw C/C++/ ,Win32
API development, VB6, MFC, etc.) to build desktop
executables. Each of these APIs provided a code base
to represent the basic aspects of a GUI application,
including main windows, dialog boxes, controls, menu
systems, and other necessities. With the initial release
of the .NET platform, the Windows Forms API quickly
became the preferred model for UI development,
given its simple yet very powerful object model.

4.  Desired Functionality
 Building forms with controls
 2D graphics support
 3D graphics support
 Support for streaming video
 Support for flow-style documents
 .NET 2.0 Solution
 Windows Forms
 GDI+ (System.Drawing.dll)
 DirectX APIs
 Windows Media Player APIs
 Programmatic manipulation of PDF files

5.  After .net 3.0 for all of the above problems there is a
solution given by just one technology that is WPF.

6.  Providing a Separation of Concerns via XAML Perhaps
one of the most compelling benefits is that WPF
provides a way to cleanly separate the look and feel of a
Windows application from the programming logic
that drives it. Using XAML, it is possible to define the
UI of an application via markup. This markup (ideally
created by those with an artistic mind-set using
dedicated tools) can then be connected to a managed
code base to provide the guts of the program's
functionality.

7. • A number of layout managers (far more than Windows
Forms) to provide extremely flexible control over
placement and reposition of content
• Use of an enhanced data-binding engine to bind content to
UI elements in a variety of ways
• A built-in style engine, which allows you to define
"themes" for a WPF application
• Use of vector graphics, which allows content to be
automatically resized to fit the size and resolution of the
screen hosting the application
• Support for 2D and 3D graphics, animations, and video
and audio playback
• A rich typography API, such as support for XML Paper
Specification (XPS) documents,
 fixed documents (WYSIWYG), flow documents, and
document annotations (e.g., a Sticky Notes API)
 Support for interoperating with legacy GUI models (e.g.,
Windows Forms, ActiveX, and Win32 HWNDs)

8. Applications
 Traditional Desktop Applications
 Navigation-BasedWPF Applications
 XBAP Applications
 Silverlight Applications

9. WPF Assemblies
PresentationCore.dll
 This assembly defines numerous types that constitute the foundation of the
WPF GUI layer.
 For example, this assembly contains support for the WPF Ink API (for
programming against stylus input for Pocket PCs and Tablet PCs), several
animation primitives (via the System.Windows.Media.Animation
namespace), and numerous graphical rendering types (via
System.Windows. Media).
 PresentationFoundation.dll
Here you will find the WPF control set, additional animation and
multimedia types, data binding support, types that allow for programmatic
access to XAML, and other WPF services.
 WindowsBase.dll
This assembly defines the core (and in many cases lower-level) types that
constitute the infrastructure of the WPF API. Here you will find types
representing WPF threading types, security types, various type converters,
and other basic programming primitives (Point, Vector, Rect, etc.).

10. Namespaces
 Namespace
 System.Windows
 System.Windows.Controls
 System.Windows.Markup
 System.Windows.Media
 System.Windows.Navigation
 System.Windows.Shapes

11.  XAML free Code…..
