## What it is
Reflexil is a .NET assembly editor that runs as a plugin for Reflector, ILSpy, and JustDecompile. Built on Mono.Cecil, it can manipulate IL code, save modified assemblies, and inject C#/VB.NET code.

## Use cases
- patch IL code in a .NET dll
- inject C# code into a compiled assembly
- modify a Unity3D game assembly
- edit .NET assemblies from within ILSpy
- convert a .NET GUI app to console by patching
- save modified assemblies back to disk

## When to choose
- you need to edit or patch .NET assemblies inside Reflector, ILSpy, or JustDecompile
- you work with legacy .NET Framework assemblies and IL-level manipulation
- you want C#/VB.NET code injection into compiled assemblies

## When to avoid
- you need a maintained tool - the project is discontinued as of 2024
- you target .NET Core / modern ILSpy 8+ assemblies
- you want a full-featured modern .NET debugger/editor - use dnSpyEx instead
