The using directives at the top of the C# part of Listing 2-1 are really a shortcut that
makes it easier for you to write code. For example, the System namespace contains the
Console
Console
class. If the using System directive were not present, you would be required
to write System.Console.WriteLine instead of just Console.WriteLine. This was a short
example, but using directives can help clean up your code and make it more readable.

A VB module must be declared at the global level, meaning that it can’t be added to
a namespace that you create. The following example demonstrates what a VB namespace
looks like:
looks like:
Namespace FirstProgram
Public Class Customer
End Class
End Namespace
Public Class Customer
End Class
End Namespace
In this example, you can see that the FirstProgram namespace contains a Customer
class. The next task you’ll want to take on is writing code, but before doing so, let’s look
at some of the features of the VS Code editor.

An Overview of the VS Code Editor
The VS Code editor is where you’ll be performing much of your coding work. This section
will point out a few features you will be interested in and show you how to perform
customizations. Figure 2-3 shows the editor with the Console application skeleton code
from the C# part of Listing 2-1.
