C# Basics

Question

Can you thoroughly explain to me namespace, class, and static void Main?
Please include why they are essential, what they can be substituted with, and how to know when to use substitutions.
I’m asking on here because I want multiple interpretations so that I can have a general understanding of how they work.

Answer 1

That's the job of tutorial here. The question is too general. It's like asking your math teacher, "What is math? Why is it essential?".
