## What it is
EasyHook is a Windows API hooking library that lets you intercept and extend unmanaged code APIs with managed (.NET) or native hook handlers. It supports 32- and 64-bit Windows targets and can inject .NET assemblies or native DLLs into running processes.

## Use cases
- hook Windows API functions in a running process
- inject a .NET assembly into a native application
- intercept function calls for debugging or tracing
- extend unmanaged code with managed hook handlers
- monitor API calls in 32- and 64-bit Windows processes
- build instrumentation or anti-cheat research tools

## When to choose
- you need to hook Windows APIs from managed .NET code
- you need to inject into both 32-bit and 64-bit processes
- you want a mature, MIT-licensed hooking library with COM interface support

## When to avoid
- you target Linux or macOS - EasyHook is Windows-only
- you need .NET Core/.NET 5+ injection - it supports .NET Framework 3.5/4.0
- you need a cross-platform hooking solution

## Facets
- artifact type: library
