Silverlight 5 introduces improvements to performance, controls, graphics, and elevated trust capabilities. Key changes include implicit data templates, ancestor binding, binding in styles, markup extensions, XAML debugging, text layout controls, 3D graphics, in-browser elevated trust applications, and unrestricted file system access. The beta release is feature incomplete but focuses on performance, a closer experience to WPF, and enabling line-of-business applications.

- 14. Final release soon this yearGoalsImproving performance
- 15. Getting closer to WPF
- 17. Better development experienceCairo at Night, EgyptXAML Changes
- 18. XAML ChangesImplicit Data Templates
- 22. XAML Debugging
- 23. Layout TransitionsImplicit Data TemplatesAssociated to a data type instead of a specific control
- 24. Applies to any control that…
- 25. trying to display the data type specified
- 26. have a templatable content
- 27. defined in the scope of the template
- 28. Define outside the control (e.g. as a resource)
- 29. Use DataType to specify the data type
- 30. Use binding to communicate with data
- 31. Typically used with collection controls (e.g. ListBox, ComboBox, etc.)Demo: Implicit Data Templates
- 32. Ancestor RelativeSourceAllows binding to a property on a parent control
- 33. Binding Outside the box
- 34. Implements the WPF feature
- 35. Use Binding.RelativeSource to specify the source in the tree
- 36. Use AncestorType to specify parent type
- 37. Use AncestorLevel to specify its level in the tree<TextBlockText="{BindingTag, RelativeSource={RelativeSourceAncestorType=Grid, AncestorLevel=2}}"/>
- 39. Binding in StylesAllows changing styles during runtime
- 40. Implements the WPF feature
- 41. Binding is supported directly in style setters
- 42. Use the standard binding syntax
- 43. All binding features supported (e.g. converters, formatters, etc.)<Setter Property="Foreground" Value="{StaticResource theBrush}" />
- 44. Demo: Binding in Styles
- 45. Markup ExtensionsCreate your own markup extensions
- 46. Allows you to run custom code at XAML parsing time
- 47. Examples of markup extensions: {Binding}, {RelativeSource}, etc.
- 48. Much simpler than attached properties
- 49. More concise syntax<TextBlock Text="{my:SumExtension FirstNumber=1, SecondNumber=2}" />
- 50. Markup ExtensionsImplement IMarkupExtension<T> (System.XAML)
- 51. Where T is the type of the data that you wish to return (must be reference type)
- 52. Provide properties for parameters
- 53. Implement ProvideValue() to return the valuepublicclassSumExtension : IMarkupExtension<object>{publicint FirstNumber { get; set; }publicint SecondNumber { get; set; }publicobjectProvideValue(IServiceProvider serviceProvider) {return FirstNumber + SecondNumber; }}
- 55. XAML DebuggingAllows breakpoints in bindings
- 56. Works by placing a breakpoint inside the binding in XAML
- 57. Stops on Push and Pull to the control
- 58. Use VS debugging tools to get binding details
- 59. Breakpoint condition and filters can be set
- 60. Past approaches:
- 61. Hunt through the output window for any binding failure information
- 62. Create a debug-only value converter, assign it to all bindings, and put the breakpoint inside itDemo: XAML Debugging
- 63. Layout TransitionsCreate a really rich experience without storyboards or animations just with a few lines of XAML
- 64. Not in Beta<VisualStateManager.LoadTransition><LoadTransition StartXOffset="300“ GeneratedDuration="0:0:1.0" StartOpacity="0.2"><LoadTransition.GeneratedEasingFunction><CircleEase/></LoadTransition.GeneratedEasingFunction></LoadTransition></VisualStateManager.LoadTransition>
