Synopsis

This class is an introduction to the Visual Basic 2008 (formerly VB.NET) programming language. It will cover the concepts and building blocks of the Visual Basic programming language, such as how .NET is different from traditional programming, defining variables, control structures, operators, classes and methods. It will provide delegates with a skill base from which they can go on to develop .NET applications on either the Windows Forms or ASP.NET platforms.
