Furthermore, each of these namespaces are automatically available to each *.vb file in your project. Given this point, you do not need to explicitly add a set of Imports statements to gain access to their types. Thus, if you wished to do so, you could still make use of various VB6-isms, such as the MsgBox() call to display a simple message box:

' The Microsoft.VisualBasic namespaces ' are automatically referenced by a ' Visual Studio 2008 VB project.

Module Module1 Sub Main()

MsgBox("Hello, old friend...") End Sub End Module

Notice how it appears that you are calling a global method named MsgBox() directly within Main(). In reality, the MsgBox() method is a member of a VB 2008 module named Interaction that is defined within the Microsoft.VisualBasic namespace (see Figure 2-26).
