SharpMonoInjectorCore is a tool for injecting assemblies into Mono embedded applications, made compatible with the 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.

• Windows 10 or higher
• Microsoft .NET SDK

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.

Inject

SharpMonoInjector.exe inject -p RobocraftClient -a rc15-hax.dll -n RC15_HAX -c Loader -m Load

Usage:
SharpMonoInjector.exe inject <options>

Required arguments:
-p      id or name of the target process
-a      path of the assembly to inject
-n      namespace in which the loader class resides
-c      name of the loader class
-m      name of the method to invoke in the loader class

Eject

SharpMonoInjector.exe eject -p RobocraftClient -a 0x13D23A98 -n RC15_HAX -c Loader -m Unload

Usage:
SharpMonoInjector.exe eject <options>

Required arguments:
-p      id or name of the target process
-a      address of the assembly to eject
-n      namespace in which the loader class resides
-c      name of the loader class
-m      name of the method to invoke in the loader class

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
