I also had to change to VB.net at the end of last year because vb6 didn't support MYSQL on my 64bit system.

I changed to VS2013 and had to convert my vb6 project into VS2013 completely by hand.

I programmed at the vb6 project for about 2 months and it took me about 2 weeks to convert it into VS2013

The most time I needed to find out the correct syntax in VS2013. So now i am quit fit in VS2013 and I woud do the same job within 2-3 days
