This chapter discusses the syntax of the Visual Basic .NET language, including basic concepts such as variables, operators, statements, classes, etc. Some material that you’d expect to find in this chapter will seem to be missing. For example, mathematical functions, file I/O, and form declarations are all very much a part of developing Visual Basic .NET applications, yet they are not introduced in this chapter because they are not intrinsic to the Visual Basic .NET language.

When you use Visual Studio .NET, source files are listed in the Solution Explorer window, and all source is included from these files when the solution is built.
