Introducing “vscode-csharp-autobuild”: Automatic VSIX Releases for OSS Editors

[rkttu]

Hi all,

As many of you may already know, the official C# Dev Kit require Visual Studio Community licensing, which limits their use to the official VS Code distribution. While the OmniSharp-based C# Base Language Support extension is available under the MIT License, recent changes have restricted direct downloads of VSIX packages from the VS Code Marketplace, making it increasingly difficult to set up a modern C# development environment on OSS-based editors like Cursor, Windsurf, and others.

To address this, I created vscode-csharp-autobuild, a project that automatically tracks the latest releases from dotnet/vscode-csharp and publishes custom-built VSIX packages. These packages can be installed directly on a variety of editors, regardless of marketplace limitations, allowing you to easily enable C# language support, OmniSharp LSP features, and even Visual Studio color themes.

Feel free to check out the latest releases here:

All kinds of feedback, questions, and contributions are welcome!
