dnSpy is a Windows desktop application that provides a .NET debugger and assembly editor. It lets you inspect, edit, and debug .NET and Unity assemblies even without source code.
Use cases
- debug .NET applications when source code is unavailable
- edit and patch .NET or Unity assemblies directly
- inspect and modify IL code using the built‑in hex editor
- decompile assemblies to understand their structure
- debug Unity games by loading the dnSpy‑Unity‑mono plugin
When to choose
- You need a free, GUI‑based .NET debugger with assembly editing capabilities.
- You are working with Unity or .NET assemblies and lack the original source.
- You want to quickly patch or modify compiled .NET binaries on Windows.
When to avoid
- You require a cross‑platform debugger that runs natively on Linux or macOS.
- You need advanced remote debugging or integration with modern IDEs.
- You prefer a command‑line only tool or automated scripting without a GUI.
