Beside DavidS recomendation, take a look at Workshop that will be at DevEssentials:
http://www.devessentials.com/Workshops.asp>We have a large Visual FoxPro application that is used by 150 or so clients. Looking ahead, we feel it is time to move the system into something like SQL Server/.NET, but I know nothing about these languages. Is DevTeach a good place to get started? Will anyone be there whom I can talk to personally about the migration, possibly someone who has done something similar?
