dnSpy is a Windows GUI application for debugging and editing .NET and Unity assemblies without needing source code. It combines a debugger, a C#/VB assembly editor with IntelliSense, an IL editor, and a hex editor with .NET metadata awareness.
Use cases
- debug a .NET assembly without source code
- edit and patch a compiled .NET dll
- debug Unity game assemblies
- inspect and modify IL code in an assembly
- reverse engineer a .NET application
- set breakpoints in third-party assemblies
When to choose
- you need to debug or patch .NET/Unity assemblies with no source available
- you want an integrated debugger, decompiler-style editor, and hex editor in one tool
- you need to edit low-level .NET metadata or IL bodies
When to avoid
- you need a cross-platform debugger - dnSpy is Windows-only
- you want actively developed tooling - the last release was December 2020 and the project is in maintenance
- you only need to decompile assemblies to read code rather than debug or edit them
