3Sharp gets some nice exposure in the MSDN Windows Vista and Microsoft Office Beta Experience Newsletter. In Issue 6, some of the 2007 release hands-on labs that we originally developed for PDC05 are listed. They are available as Beta 2 virtual labs on MSDN.
In addition, it appears that Issue 5 has been updated to include the building permit application solution that I started writing about in June. Like the virtual labs, this hands-on lab is also set up for Beta 2. There is a download available that includes the database, form template, and data connection files used in the solution. Unfortunately, there are no setup instructions included with the lab. So, if you run into any problems, feel free to drop me a line.
