Some have reported trouble in finding the source files for the Web and Smart Client session for the launch 2005 event DVDs. They should be in a folder entitled WhidbeyRocks but if you are still having trouble finding them and would like them immediately, ping me a note at jcarron@microsoft.com and I'll email them out to you.
 
I've prepared a zip files for the Web and Smart Client. In order to keep the size down I've not included the automatically pre-configured SQL Express database that stores membership information etc… If you want to reconfigure it using SQL Server or are unsure how to create the Application Services database then have a look at this article on MSDN.
