The Architecture of WPF

The architecture of WPF is multilayer.

WPF API  

• PresentationFramework.dll
• PresentationCore.dll
• WindowsBase.dll

Media Integration Layer

• Milcore.dll,
• WindowsCodesc.dll

User 32, Direct 3D

Direct3D renders all drawing WPF.

All display in WPF is done through the DirectX engine -> efficient hardware and software rendering

              

DispatcherObject

• Uses User32 messages for performing cross thread calls

What is Windows Presentation Foundation (WPF) ?

Windows > Controls > Binding > Printing > Resources

Windows Presentation Foundation (WPF) is a UI framework that creates rich, interactive client applications.

WPF combines application UIs, 2D and 3D graphics, documents and multimedia into one single framework.
The WPF development platform supports a broad set of application development features, including an application model, resources, controls, graphics, layout, data binding, documents, and security.
It is a subset of the .NET. Its vector based rendering engine uses hardware acceleration of modern graphic cards. This makes the UI faster, scalable and resolution independent.

WPF uses the Extensible Application Markup Language (XAML) to provide a declarative model for application programming.

Examples:

• Create a simple Hello World application

 

Create a simple ‘Hello World’ WPF application

WPF > First application

Create a simple ‘Hello World’ WPF application

Go to menu File - > New Project and then Visual C# -> Windows -> WPF Application.

 

Visual studio automatically creates the project and adds some files: MainWindow.xaml and MainWindow.xaml.cs
Double click on MainWindow.xaml and from Toolbox window drag a button and a label. Name label “lblTtitle”.

 

Double click button and add the following code: lblTitle.Content = "Hello World!";

 

Press F5 to run the application
