You gotta love SeeWindowsVista
Have you checked out https://www.seewindowsvista.com/???
It is a very cool way to see some amazing things that developers are doing with Vista and .NET Framework 3.0. The site is clearly focused at end-users, but as a developer you might want to know what technology bets it took to make those apps.. I did a little poking around and here is what I was able to find out.... If there is some specific showcase you’d like to find more about please let me know.
