First and foremost, thanks to all of you that attended my presentation! We had a great crowd that was eagered to learn more about the inner workings of ASP.NET. Second, I would like to apologize for my buggy demo. Like I mentioned during the error, I moved the database file containing the content from my desktop to a folder under the C-drive so my connection string got hosed. I didn't take the time to check the demo to its entirety before showing it. My apologies.
If you would like to get the demo code for the presentation, you can do so here.
Thanks for making HDC a huge success!
