Answer 8

now I understand. The using directive.

It is a shortcut label to the libraries that are referenced.

if you have a line
using System;
Console.WriteLine("hello world");

if you also may write
using System.Console;
WriteLine("hello world");

If you use WriteLine a lot, it saves you from typing.
And there is a lot less code

On the otherside it can be confusing, because you can't read from which class the WriteLine is
Also a WriteLine from a other class can give conflicts if you do not type the full name.
