## What it is
ConfuserEx is a free, open-source protector for .NET applications that provides obfuscation features such as symbol renaming, control flow obfuscation, constant and resource encryption, and anti-debugging/anti-tampering protections. It offers both a command-line interface and a graphical interface, and is the successor to the original Confuser project.

## Use cases
- protect .NET applications from reverse engineering
- obfuscate C# assemblies to prevent decompilation
- rename symbols in .NET binaries including WPF/BAML
- encrypt constants and resources in .NET apps
- add anti-debugger and anti-tampering protection to .NET software
- compress and embed dependencies into a protected .NET output

## When to choose
- you need to obfuscate a .NET Framework 2.0-4.5 application for free
- you want commercial-protector-level features like control flow obfuscation and method encryption without paying for a license
- you need a plugin-extensible obfuscation pipeline for .NET assemblies

## When to avoid
- you are targeting .NET Core, .NET 5+, or modern .NET runtimes beyond .NET Framework 4.5
- you need an actively maintained tool with bug fixes and community support, since this project is discontinued and unmaintained
- you require guaranteed protection against determined attackers, as obfuscation is not a security boundary

## Facets
