ilspy-vscode (Extension)

This is the actual VSCode extension part of the project, which fulfills following tasks:

• Integrates ILSpy UI elements (like Assembly Tree, Search and Analyze panels, palette commands) into VSCode shell
• Manages extension settings (global and workspace-specific)
• Controls backend process launching it at startup and initializing it with configuration
• Installs a required version of .NET runtime using Microsoft's .NET Install Tool for Extension Authors

A description of the extension's features can be found in Feature Tour.

Export decompiled code

To export all decompiled code of a loaded assembly, right-click the assembly node in the ILSpy: Assemblies view and run Export Decompiled Code.... This will generate a complete C# project including:

• All decompiled source files organized by namespace
• A .csproj project file for easy compilation

Requirements

• Visual Studio Code >= 1.101
• .NET 10.0 (installed automatically on first start)
• Node.js (22 or newer)
• PNPM

Development

To debug and run the extension, you first need to build and package the backend:

cd ..
buildtools/publish-backend

The backend's binaries are automatically copied to vscode-extension/bin/ilspy-backend, where the extension expects them.

Then initialize the project with

pnpm install

Open this directory in Visual Studio Code and start debugging with F5. A development instance of VS Code will open with the latest extension code running.
