Welcome to my advent of code 2020 contribution! The solutions are written in C# using .NET 5. When writing the solutions code I primarily aim for readability but try to always keep performance considerations in mind. Happy reading!
For running the code you need the .NET 5.0 SDK installed. Run the code via
dotnet run
You can also have a look at my repl at https://repl.it/@thejan14/adventofcode2020 where I run the code using Mono.
Please note that I may exclude solutions for running on repl if they use C# 9.0 features as Mono only supports up to C# 7.0.
