They did?   Service Pack 1 for .Net Framework 3.5 has been available for a while (November 2008), but I haven't heard of any other specific update for it... unless they've been released via Windows Update?
Good evening, Microsoft recently sent their Vista users an update for .Net Framework 3.5.  Will someone direct me to the link for that update. Thank you, Nissi1
