About
ILSpy is an open-source .NET assembly browser and decompiler maintained by the icsharpcode team. It decompiles compiled .NET assemblies to C#, supports whole-project decompilation, and includes a metadata explorer, type/method search, hyperlink navigation, and ReadyToRun binary support for .NET Core. The desktop UI is built on Avalonia and runs on Windows, Linux, and macOS.
Besides the desktop app, the decompiler engine is available through several frontends: a Visual Studio extension, a Visual Studio Code extension, the ilspycmd dotnet tool, PowerShell cmdlets, and the ICSharpCode.Decompiler and ILSpyX NuGet packages for embedding in other projects. Recent Visual Studio versions also ship built-in F12 decompilation based on its engine. The command-line tool and libraries make it usable from scripts and automated workflows, including AI agents that inspect .NET binaries, as mentioned by one YouTube creator.
ILSpy is not an AI product itself. It is a conventional decompiler, and output quality depends on the language features used in the original assembly (see the project's language support status). It is distributed under the MIT License; the repository dates from 2011.
