WPF is Microsoft's presentation framework that uses XAML and .NET to create desktop applications. It allows developers to separate UI from code and use a graphics-based rendering engine. WPF supports data binding, styles, templates and themes to customize the user experience. Expression Blend can be used by designers to work on the UI without requiring code.

3. What is Windows Presentation Foundation? It’s part of WinFX (.NET 3.0) It’s XAML (just like [HT]ML) and .NET 2.0 It’s a unified approach to code, UI, documents and media It’s not HWND It runs in Windows (XP too), Web and even /E It works mostly using the GPU

4. So XAML or Code Compile and Run Compile and Run Parse 010010100101101001010101101010100 BAML Load and Display < Button Width =&quot;100&quot; Background =&quot;LightBlue&quot;>OK</ Button > Button b = new Button(); b.Width = 100; b.Background = Brushes.LightBlue; b.Content = &quot;OK&quot;; Dim b As New Button b.Width = 100 b.Background = Brushes.LightBlue b.Content = &quot;OK&quot;

5. … or Both CLASS Compile and Run public partial class internal Button b; Load(“app.baml”); 010010100101101001010101101010100 app.baml Parse and Generate < Button Width =&quot;100&quot; Background =&quot;LightBlue&quot; Click =&quot;DoSomething&quot;>OK</ Button > void DoSomething(object sender, RoutedEventArgs e) { MessageBox.Show( &quot;I do not have to do designer's work!&quot;); }

9. Dependency and Attached Properties Dependency Property Globally registered static property Handles storage and property changes Implement a dependency properties when visual or logical inheritance, or invalidation is required Attached Property Specialized form of dependency properties Child elements store unique values on parent Child informs parent how to present it on the UI If parent not found, attached property is ignored Property Engine Input / Eventing System .NET Framework 2.0 Unmanaged USER INTERFACE SERVICES Property System Input & Eventing BASE SERVICES DOCUMENT SERVICES MEDIA INTEGRATION LAYER

10. DEPENDENCY AND ATTACHED PROPERTIES WPF Properties Systems – base concepts

13. Data Binding UI can be bound to any data driven object Dependency properties can be even bounded to ADO.NET and Web Services All operations (filter, sort, group) are generated on top of the data You can apply Data Templates to the data What can be a data binding target Any FrameworkElement Any DependencyProperty Binding Target Binding Source Dependency Object Object Dependency Property Property TwoWay OneWay OneWayToSource

14. DATA BINDING WPF Data Binding

16. Visualization engine and Styling Dependency Properties = binding, styling, triggers, animation Template = customized experience Removed explicit relationship between code & UI Empowered application designer to create custom visuals USER INTERFACE SERVICES XAML BASE SERVICES DOCUMENT SERVICES Composition Engine MEDIA INTEGRATION LAYER Controls Layout
