Solutions to the Advent of Code programming puzzles in C# .NET 5. I'm using .NET 5 so that I don't get too far ahead of what Unity supports.
Originally forked from ShootMe/AdventOfCode to use their excellent infrastructure, utility classes, and puzzle class templating as a starting point.
All puzzle solutions are my work. Re-created this repo after 2021 Puzzle 8 so that my work on it shows up in my Contribution activity.
