A very simple system to load DLLs at runtime for the Coffee Please beta. The repo contains three Visual Studio 2017 projects: the mod loader, my janitor mod source, and my more console commands mod source.
In both projects you'll have to either go into visual studio and fix the missing references (files can be found in your game's data directory/Managed) OR go into the .csproj files and replace "REPLACETHISWITHYOURUSERPATH" with the path to your user profile (e.g. C:\Users\Johnny)
Copy the Assembly-CSharp and ModLoader dlls I've provided (use the releases tab to get them) for your version into your game's data directory/Managed
After compiling a mod, copy it to the game's data directory/Modding/Assemblies If the Assemblies folder does not exist create it.
