Almost missed this important milestone release info while busy working too many stuff at work.
- Application Model
o WPF builds on the new add-in model in .NET Framework 3.5 Beta 2 to allow developers to create visual add-ins, where add-ins provide UIs that are displayed by the host application. You’ll find the add-in types in the System.AddIn namespace in System.AddIn.dll, System.AddIn.Contract.dll, and System.Windows.Presentation.dll.
o XBAPs can now run in FireFox.
o Cookies can be shared between XBAPs and Web applications from the same site of origin.
o Improved XAML intellisense experience for higher productivity.
o Data binding and journaling by URI work together.
- Data Binding
A new debugging mechanism makes it easier to debug data bindings. (new attached property: System.Diagnostics.PresentationTraceSources.TraceLevel)
o The data validation model now supports the IDataErrorInfo interface. (new class: System.Windows.Controls.DataErrorValidationRule)
o Improvements have been made to BindingListCollectionView to provide better support for binding to a collection that is of type BindingList and for LINQ.
o The behavior of data bindings with a CollectionView over an IEnumerable has been improved to provide better performance and better support for binding to results that are produced by LINQ.
- UIElement concepts such as input, focus, and eventing have been brought to 3D. (new classes: System.Windows.UIElement3D which is abstract, and ContainerUIElement3D and ModelUIElement3D in the System.Windows.Media.Media3D namespace)
- Developers can now place interactive 2D content onto a 3D object. (new class: System.Windows.Media.Media3D.Viewport2DVisual3D)
- The annotations framework now exposes the capabilities for matching annotations with the corresponding annotated objects. (new interface IAnchorInfo and new class TextAnchor in the System.Windows.Annotations namespace)
- Better IME support, RichTextBox extensibility (new property IsDocumentEnabled), performance improvements, and more!
I will be playing with the new Beta 2 soon! No more frustration over the half-supported XAML IntelliSense in VS 2005 (with Cider). Oh, by the way, this beta 2 has a Go Live! license. Perfect! 🙂
