>Just for asking. Why do you choose VB.NET instead VFP to develop your apps? Could you give some advantages, maybe particular reasons found or experienced by you?

That really depends.

What kind of app is it? (Windows,web,console,service,device driver?)
Will it have a data store?
How will it be deployed?
Who will be the users, do they care what it is written in?
What is your expertise?
