I agree with you that C# is easy enough to learn for a Foxer. I don't agree that NET allows you to work with larger databases. We began using SQL Server with Fox even before VFP was released in 1995.
IMHO the main Fox claim to fame was its local indexed "cursors" that span automatically to disk, meaning you can do anything you like locally without overwhelming local resources to bring the machine to its knees. It was fashionable to scoff at this concept for most of the last 7 years but people are coming back to it. Perhaps NET will get this ability soon- or perhaps some better way will be invented as mobile devices with no hard drive and unpredictable connectivity come to dominate the front end.
"... They ne'er cared for us
yet: suffer us to famish, and their store-houses
crammed with grain; make edicts for usury, to
support usurers; repeal daily any wholesome act
established against the rich, and provide more
piercing statutes daily, to chain up and restrain
the poor. If the wars eat us not up, they will; and
there's all the love they bear us."
-- Shakespeare: Coriolanus, Act 1, scene 1
