My name is Andreas Pardeike, aka Brrainz, or the creator of Harmony. This guide is my personal attempt to help everyone through the journey of upgrading their mods. I am not affiliated with LUDEON studios or with developing RimWorld. It's just a personal thank you from me to the community.
This guide will help modders to update their C# mod to RimWorld 1.1. I will tell you how you upgrade to Harmony 2 and why. It will also serve as a guide to common changes that I encountered while I upgraded my own Camera+ mod. During the guide, I will use Visual Studio 2019. It's community edition is free. If you use a different IDE, please adapt your changes.
