A few days ago (feels like a week, but what a week!) I wrote “PDC05 - Hey, who did the amazing "North Face" Demo at the PDC?”. This was about the Fluid guys doing a keynote demo highlighting the Windows Presentation Foundation (WPF).
Darren of Fluid and Karstens of Microsoft wrote a whiteper titled “The North Face In-Store Explorer Proof-of-Concept: A White Paper”, now available on MSDN. It has a great deal of information on how they did it, including code and XAML samples. Amazing work, guys.
See the magic again! Watch the video of the demo.
