Solutions

This repo contains my solutions to the Advent of Code 2025 using primarily C#.

The code will likely be bad. :p

Setup

dotnet tool install -g dotnet-script

dotnet tool update dotnet-script -g

• dotnet-script [1.6.0]

Copy the 📂 day folder and use.

Running Solutions/Tests

How to run the solution file for each day depends on the language.

C#

Any C# scripts will require dotnet-script and ScriptUnit.

• dotnet script tests.csx

or

• dotnet script dayXX/solution.csx
• dotnet script dayXX/tests.csx
