BepInEx fork of Il2CppAssemblyUnhollower is now Il2CppInterop!

Looking for old README and guides? Check out legacy-unhollower branch.

Il2CppInterop is a framework for bridging together Unity's Il2Cpp and .NET's CoreCLR runtimes. The framework various interoperability tools:

  • A tool to generate .NET assemblies from Cpp2IL's output.
  • A runtime library to work with Il2Cpp objects in CoreCLR.
  • Libraries to integrate other tools with Il2Cpp.

The framework allows the use of Il2Cpp domain and objects in it from a managed .NET domain. This includes generic types and methods, arrays, and new object creation.

This project started out as fork of knah/Il2CppAssemblyUnhollower but has been since been modified with new API and fixes to be a standalone project.
