Can you please advice on this? Sorry if this has been asked before I did some search but no results.

I'd like to start with asp.net but am not sure which program language to learn. My main objective is to be able to develop dynamic content web sites using asp.net, SQL, Access.

I think I have the following to choose from according to asp.net site but not sure what c# is. Is it c++, c or other language all together?

C# Source: CS\Intro2.aspx
VB Source: VB\Intro2.aspx
JScript Source: JS\Intro2.aspx
VJ# Source: VJS\Intro2.aspx

Ideally, I’d like to go for the easiest to learn and the most portable.

Any tips or pointers to tutorial sites I'd be much appreciated.
