Yesterday, on Krakowska Grupa Deweloperów .NET, I gave a presentation, together with my friend Arkadiusz Świerczek, on latest Microsoft .NET Framework 3.5 SP1 WPF stuff and WPF Tips & Trick.
We didn't have enough time to cover all the goddies we've prepared, but we managed to introduce some basics around WPF and present WPF effects in pixel shader. Besides, we've presented how to write multi-language, runtime bound UI, skins and a rapid introduction to attached behaviors.
The presentation together with full sources can be downloaded from here. Enjoy!
