SharpMonoInjectorCore

SharpMonoInjectorCore is a tool for injecting assemblies into Mono embedded applications, made compatible with Microsoft .NET Core. The target process may require a restart before injecting an updated version of the assembly. Your unload method should destroy all allocated resources to prevent any memory leaks. Both x86 and x64 processes are supported. You can see an example implementation here.

Requirements

Windows 10 or higher
Microsoft .NET SDK

Concept

SharpMonoInjector works by dynamically generating machine code, writing it to the target process, and executing it using CreateRemoteThread. It calls functions within the Mono embedded API. The return value is obtained with ReadProcessMemory.

Build

dotnet publish

Submodule

If you plan to package this along with your cheats, I would recommend that you add this repository as a git submodule.

mkdir submodules
git submodule add --depth 1 https://github.com/winstxnhdw/SharpMonoInjectorCore.git ./submodules/SharpMonoInjectorCore
git config -f .gitmodules submodule.submodules/SharpMonoInjectorCore.shallow true

To update your submodule later, simply run the following.

git submodule update --remote
