PDC2008 – Declarative Programming using XAML
Several technologies have leveraged XAML since .Net 3.0 : WPF, WF, Silverlight, XPS.
State of XAML 2006
- Need language evolution
- Make it faster
- Compilation, debugging, obfuscation, localization, FxCop, VS Integration
- A lot of people write their own parser => XAML ready framework
In .Net 4, we will ship XAML 2009.
XAML 2009
- x:Reference name (Backward and forward references) and target attribute (possibility to point to a reference)
- built-in types (set of basic types)
- generics (x:TypeArguments)
- arbitrary key types (x:Key)
- beyond method names (no more markup compilation, and delegates)
- better declarative type authoring (x:SchemaType)
- w:FactoryMethod
XAMLPad enhancements to represent the XAML Data Model is too flexible : OMV (Object – Members – Values
System.Xaml.dll in .Net 4.0.
- a November 2008 CTP will be released, will work on .Net 3.5
- XAML to objects processing: XamlReader.Load. XML Node to XAML Node and XAML Node to Objects + type resolution.
- XamlXmlReader (XML => XAML)
in .Net 4.0, WF vocabulary will get richer (DataFlow) and a rich WCF vocabulary will be introduced. Thus, you can have an entire application (UI + Business Logic + Services invocation + Workflow) implemented in XAML.
To benefit from XAML, have your framework XAML ready. Ride the XAML wave.
