VB.net programming Elements Support Change summary

Visual Basic 2005 Changes the way it supports various programming elements, primarily to provide interoperability with the common language runtime. Many Visual Basic 6.0 elements are renamed, re-categorized, or combined with other programming elements of Visual Basic 2005. Support for several elements is canceled because the functionality in the common language runtime (CLR) makes it unnecessary for these elements to exist. For more information, see Common Language runtime.
For additional information about Visual Basic changes-including the integrated development environment (IDE), WEB features, projects, forms, constants, and the Circle, line, and Pset methods, see Help for users of Visual Basic 6.0.
