And though the new Visual Basic Runtime provides similar facilities as its predecessors, it is entirely managed code (developed in Visual Basic .NET) that executes on the common language runtime. Furthermore, the Visual Basic Runtime is part of the .NET Framework, so it is never something separate that your application has to carry or deploy.
Many of the methods in the Visual Basic Runtime actually use methods and properties from the System namespace (for example, Len() returns String.Length).
