Can't make it to TechEd: Developers or MobileConnections and want to learn how to build gadgets for Windows SideShow?  I'll be doing a webcast on November 28, 2006 at 10am PST on MSDN and show you what you need to know to get started.  I haven't yet finalized my slides, but I can tell you this will be a good overview on SideShow gadget development, including basic and some more advanced topics.  I'll also demo and discuss both our new managed API and Sidebar integration, which make it even easier to get going.  For those who can't make it to the live webcast, I believe it will be available on-demand at some point after completion (I'll post more info on this when I have it).  Here is the registration URL:
