XAML today
If your like me and can't wait for Longhorn (or if your also like me and your PDC Longhorn alpha code runs like a bag of spanners) but your curious about XAML then a few products for writing XAML apps for 1.1 of the CLR are starting to show up. I have just started looking at
Xamlon but another product is
Mobiforms XAML browser and user control.
