C# 9 Simplified Console Apps

At Microsoft Build 2020, an interesting new “see less boilerplate” feature from C# 9 was demonstrated.

It removes all the code to create the class and static Main method, letting you just start typing your code. It makes your code way-less-nested (okay, two levels), but doesn’t miss any of your usual features.

For example, args is still available, and if you use an await it will work out the Main method (which you haven’t written) will need to be async.

Here’s an example…

using static System.Console;

WriteLine("Hey, I didn't write a class or method here!");

The concept behind this is to simplify that first-write experience to remove the cruft and focus everything on your code.
