VisualBasic.Compatibility Namespace

Functions and objects in the VisualBasic.Compatibility namespace are provided for use by the Visual Basic 6.0 to Visual Basic 2008 upgrade tools. In most cases, they duplicate functionality that can be achieved using other parts of the .NET Framework; they are necessary only where the Visual Basic 6.0 code model differs significantly from the .NET implementation.
