To build the project, you need to place the following dll files into the dlls directory:
- Assembly-CSharp.dll
- However, make sure to publicize it first https://github.com/BepInEx/BepInEx.AssemblyPublicizer
- Unity.Netcode.Runtime.dll
These can be found in the Lethal Company/Lethal Company_Data/Managed/ directory.
The project should now build successfully, and your shiny new dll file can be found in bin/Release/netstandard2.1/
