I wrote a ton of vb6 in the 90s. Then vb.net 2003 in... Well that date. Then moved to c# after holding on for awhile.
My memories of that time:
its higher mental load to do the right, safe thing in vb.net vs the same objective in c#.
both early versions of both languages had really similar capabilities, as they both compiled to the same IL code targeting the same VM.
these differences obviously moved apart as the years went by as the cost to innovate in 2 places is wasted effort... So language enhancements went into c#.
These days you might as well learn pascal as vb... If you want to know where to invest your time in learning i would suggest C#, java or golang for backend. Or typescript. Typescript is good.
