Are you talking about opening the 1.1 code in VS 2008 and having it convert it to 3.5? I know you can open projects in 2008 and target the 2.0 framework.Anybody who has actually tried realizes that this is not the case.
IMHO it's more useful to emphasize the major NET improvements that have occurred rather than trying to sideline them- especially to try to trick people into believing in 100% backward compatibility. Backward compatibility is not NET's strength, period. NET's strength in MS's commitment to keep making it better and get it right. That can be a PITA along the way but we might as well be accurate about the reasons we use a tool and the consequences of it.
"... 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
