This is a fork of the EasyHook project.

EasyHook supports extending (hooking) unmanaged code (APIs) with pure managed ones, from within a fully managed environment on both 32-bit and 64-bit versions of Windows Vista x64, Windows Server 2008 x64, Windows 7, Windows 8.1, Windows 10, and Windows 11.

EasyHook currently supports injecting assemblies built for .NET Framework 4.0+ and can inject native DLLs.

For native C++ apps there is also a native NuGet package: nuget.org/packages/EasyHookNativePackages
