Harmony 2.2

Introduction

Harmony gives you an elegant and high level way to alter functionality in applications written in C#. It does this at runtime by monkey patching methods unlike other solutions that change the content of dll files.

It supports Mono and .NET environments on Windows, Unix and macOS except when Unity uses the stripped down NetStandard profile (.NET 4.x profile works fine). Harmony is used in mainstream Unity games and many other applications.

Designed to be used by multiple users (usually called Mods) that would otherwise override each others hooks, it was originally created for the game RimWorld and its large modding community by Andreas Pardeike.

Enjoy!

Getting Started

Installation is usually done by copying and referencing 0Harmony.dll from your project or by using the Lib.Harmony nuget package.
