Game architecture. How to separate the menu from the game loop?

Question

.NET

Hello.
My question is for professional developers who know what, how and why.
I am familiar with the basics of C#. Including OOP.
There are difficulties with understanding delegates and events, i.e. how it works.
I'm planning to write a game. No Unity, Win Forms or Monogame. Start simple.
And here on simple, the question arises!
There is a menu. Let's say 3 points. Play, "Settings" and "Exit".
How to separate all these 3 cycles? Main menu, settings menu and game loop?
In Python, I wouldn't bother, but in C#, the model is OOP, and you have to do it the smart way.
How? And most importantly, what is the right way?
Thanks in advance!

Answer 1

maybe you need to meditate here - Event loop
and here - command based application event loop ( upd in this place you can and should creatively change the request until it is completely enlightened)
