I want to build a client applications for desktop with NET Framework and MySQL database.
i can create new project with windows form control library or windows forms app.
What is the difference between this to options?
Which of the two do you recommend using and why?

thank you in advance,

André

I'm going to decline writing a long answer. I will say I use the windows forms app.

As far as I know, windows form control library is for building custom controls. You wan windows forms app.
