>I´ve just heard some comments from a collegue about VFP is inside .NET 2003. I'm sure this is wrong because I never read something like this. However I wouldn't like to be the most intelligent and I prefer to ask about it, so...

Visual FoxPro isn't inside of Visual Studio .Net but there is a "Visual FoxPro Toolkit for .NET" which simulates some of the Visual FoxPro commands in .Net. See http://www.gotdotnet.com/team/vfp/

No
