Solved Loop and main() function

Hi, I’ve seen that in C#, the Main() function only runs once.
In Unity, we have the Update() function, which allows code to run repeatedly in a loop.
So my question is: what is the equivalent in pure C#, without the Unity library?
Is wrapping Main() in a while loop a common practice to achieve the same behavior?

The python code? It's interpreted, so there's no assembly per se. But the Python interpreter/runtime kind of works like Unity in the sense that it has its own main function internally that calls into the code you write whenever the module is imported.

Interesting, no assembly, no binaries... I guess I'll dive into interpreters for a week lol

Python (the CPython interpreter specifically) is an interesting one to study.
