WPF is Microsoft's technology for building desktop applications and uses XAML as its UI definition language. It provides capabilities like 2D/3D graphics, animations, vector graphics and a rich typography API. There are different types of WPF applications like traditional desktop apps, navigation-based apps, and Silverlight apps. The core WPF assemblies are PresentationCore, PresentationFramework and WindowsBase and it defines namespaces like System.Windows for the base UI classes and System.Windows.Controls for the built-in controls. XAML allows separating the UI definition from code and is a key part of WPF applications.

- 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)

- 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.).
