Skip the whole thing, and take what you know and press it into service learning .NET. I hear there is a dearth of .NET programmers, and it is different enough from
VB that some call it
VB.NOT; yet it is similar enough that you could probably pick it up multiple times faster than someon who does
not know
VB yet.
