ILSpy

AvaloniaILSpy is a cross‑platform version of the ILSpy .NET decompiler built with the Avalonia UI framework. It runs on Linux, macOS and Windows, allowing users to decompile .NET assemblies, view the generated source code, and navigate types, methods and properties via hyperlinks. The interface includes a search window for locating members by substring and an analysis window that presents metadata about the examined assembly.

The application is extensible through MEF, supporting custom plugins placed in the TestPlugin folder, though it does not support the original ILSpy plugins. Build artifacts are provided for stable releases and for the latest master CI builds, and the program can be launched directly from the command line on Linux or macOS after granting execution permissions.

Although the repository has been archived and is no longer actively maintained, it remains usable for developers who need a graphical .NET decompiler on non‑Windows platforms, with source code available for building from . using .NET 6 or newer.
