• Screenshots of ASP.NET Whidbey
  
  Several folks have pinged me asking for screenshots of my keynote demo to see what the final output looked like. Note that none of the scenarios shown in the screenshots (data, navigation, security, master pages) required any code out of the box. Nor was any code generated by Visual Studio. All of the controls and scenarios, however, have a very rich object model and set of events which enables rich code based customization if you have a scenario that needs it.
  
  
• How you can get PDC material without going to the PDC...
  
  One of the things we are planning on doing from the ASP.NET + Visual Studio Web Development side it to post all of our PDC talks+demo code, along with our Hands On Labs, and two Whidbey whitepapers on the http://www.asp.net website.
  This will enable people who can't make the PDC to still get a pretty in-depth taste of Whidbey (not as good as attending the talks themselves -- but still pretty deep). The exact url of the content is still TBD (we won't launch it until the week of the PDC) -- but I'll post it here so that folks will be able to easily find it.
