As an ex-VB3/5/6 programmer (hallelujah for .NET!), I can assure you that nothing will coax me back into using good ol VB, now that excellent nu C# is an option.
Not even job-saving productivity :-)
You'll come around. I did. I used C# almost solely for a year and then "re-discovered" VB.Net for it's coolness and ease of use.
It's about knowing what to use at the right time. You'll find that a lot of things have changed. It's safe to return :)
