The system is built loosely on the original BASIC programming language released in 1963 and it can 'Test' programs in real-time, error checking them in a user-friendly way.

This package is the 'backbone' of Visual Basic .NET. When applications are created, the Windows Installer includes the framework with it. It includes all the items needed to run the VB.NET applications that have been made.

<syntaxhighlight lang="vbnet"> Public Sub button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles button1.Click
MsgBox("Hello World")
End Sub </syntaxhighlight>
