The ILSpy extension for VS Code is an implementation of ILSpy .NET assembly browser and decompiler running inside of Visual Studio Code UI - in contrast to the ILSpy desktop application running standalone on Windows systems.

Please see the Feature Comparison List for the differences between ILSpy desktop application and the VS Code extension.

You can install the extension in Visual Studio Code via the marketplace.

Please see the Feature Tour to explore the extension's features.

Please see the Change Log.

If you have issues during installation of .NET Runtime, please see here.

The extension consists of two parts: The VSCode extension itself (written in TypeScript) and a "backend" server process (written in C#), which provides a bridge to ILSpy functionality.

If first time

npm i @vscode/vsce -g

Compile and package all parts:

./buildtools/publish-backend
./buildtools/build-vsix

An installable .vsix file should be generated in artifacts folder, if everything is fine.

Compile only backend server from console:

cd backend
dotnet build

Run backend tests:

cd backend
dotnet test

Or open backend/ILSpy-backend.sln in Visual Studio 2022, Visual Studio Code or JetBrains Rider.

To develop and debug the VSCode extension, install Visual Studio Code, then run

cd vscode-extension
code .
