Just learning .NET and compared to other stacks, the project structure is very confusing to me.

I am doing Advent of Code and I would like to have separate folders for each day, e.g. Day 1, Day 2.. and each folder would have its own Solution.cs.

But when I try to run it, I can only run Day 1 solution.

I would just like to run each Day on its own, for example like with python python3 day1.py – that simple.

Can someone explain how .NET Project structure works and how can I set it up.
