Introduction to BepInEx

(If you understand how BepInEx works and what it does, you can skip this and go to the next section.)

Modding Unity games is pretty standardized in 2025. In general, you have to create your mod code in C#, build it into a DLL file, then convince the game to execute your code.

There are two ways of doing this. The first is if the game has a mod loader built in, you just have to create and install mods based on their instructions. Games that work like this include Rimworld and Oxygen Not Included, and games that work like this generally have Steam Workshop support or some other standard way of distributing mods.

The other way is that if the game doesn't natively support mods, you can use BepInEx. BepInEx is a modloader, similar to Fabric for Minecraft. BepInEx works by placing a winhttp.dll file in your game folder, which does all the same things as the winhttp.dll file in your System32 folder, but it also tells it to load the code in the BepInEx DLL. From there, BepInEx can de

The Visual Studio Tools for Unity are able to convert .NET debug symbol files (namely pdb files) to debug symbols files that are understood by Unity's scripting engine (namely .dll.mdb files) when importing both the .dll and the .pdb in the Assets folder.

If you prefer to handle the conversion yourself you need to call a tool named pdb2mdb on the .dll associated with the .pdb:

pdb2mdb MyLibrary.dll

Will produce a MyLibrary.dll.mdb usable on Unity if MyLibrary.pdb is present.

To remove a submodule you need to:

Delete the relevant section from the .gitmodules file.
Stage the .gitmodules changes git add .gitmodules
Delete the relevant section from .git/config.
Run git rm --cached path_to_submodule (no trailing slash).
Run rm -rf .git/modules/path_to_submodule (no trailing slash).
Commit git commit -m "Removed submodule "
Delete the now untracked submodule files rm -rf path_to_submodule
