The Azure Services Training Kit - PDC Preview which contains the Hands on Labs that folks are doing at the PDC is now available for download.
From the download page:
The Azure Services Training Kit will include a comprehensive set of technical content including samples, demos, hands-on labs, and presentations that are designed to help you learn how to use the Azure Services Platform. This initial PDC Preview release includes the hands-on labs that were provided at the PDC 2008 conference. These labs cover the broad set of Azure Services including Windows Azure, .NET Services, SQL Services, and Live Services. Additional content will be included in future updates of this kit.
Jim, our team's PM, points to the Hands On Lab walkthroughs folks have been getting through at the PDC.
