In case anyone is interested, there is a live running version of CycleMania (the application that will accompany ASP.NET 4.0 Website Programming: Problem - Design - Solution
) that you can play with without having to download any source code:
The live site is updated via continuous integration on each build. New builds are being released about once per day.
It's not the fastest server in the world, and it's running in a VM, so if the db times out just hit it again. ;)
