Update from MEDC 2006!
At MEDC 2006, I talked about the VSD core connectivity architecture and uncovered some of the interfaces that were shrouded in mystery. Also, Alex Feinman (NETCF MVP), showed two cool demos with code examples of how to use the CoreCon API to write simple tools.
Alex's sample code is now available on OpenNETCF. Using this sample, you will be able to do datstore enumeration, connect to device, use Corecon Transport Streams, etc.
If you have any questions, you may post them on the MSDN forums at: http://forums.microsoft.com/MSDN/ShowForum.aspx?ForumID=34&SiteID=1
