Using Static Directives

From now on, you can include static directives by using the static keyword after using.

For example, System.Console exposes several static methods that we use for printing values to the console.

By referencing it statically, we can omit the name of the class when calling its static method:

using static System.Console;

And we call it:

// Console.WriteLine("Hi, there!");
WriteLine("Hi, there!");

Idea

This is the idea: you reference static classes with static to use their methods directly as if they were defined in this class.
