What Is Visual Basic .NET?

Visual Basic .NET is the next generation of Visual Basic, but it is also a significant departure from previous generations. Experienced Visual Basic 6 developers will feel comfortable with Visual Basic .NET code and will recognize most of its constructs. However, Microsoft has made some changes to make Visual Basic .NET a better language and an equal player in the .NET world. These include such additions as a Class keyword for defining classes and an Inherits keyword for object inheritance, among others. Visual Basic 6 code can’t be compiled by the Visual Basic .NET compiler without significant modification. The good news is that Microsoft has provided a migration tool to handle the task (mostly, anyway). Code migration is explained in Appendix A. The Visual Basic .NET language itself is detailed in Chapter 2.

Over the last several months I have spent almost all of my time playing with .NET and writing Visual Basic .NET programs. As a user of Visual Basic since Version 4, I can tell you that I am pleased with this new technology and with the changes that have been made to Visual Basic. In my opinion, Microsoft has done it right.
