The C# for Visual Studio Code extension is an official Visual Studio Code extension that provides rich language support for C# development.
The extension solves the problem of bringing comprehensive C# development capabilities to Visual Studio Code by leveraging a Language Server Protocol server powered by open source components including Roslyn and Razor. This approach delivers type information, code navigation, and IntelliSense directly within the editor while maintaining reliability and performance.
The extension is recommended for use alongside C# Dev Kit, which automatically installs it as a dependency, though it can function as a standalone extension. It suits developers working with C# projects that target .NET 6 or later. For projects requiring earlier .NET versions or non-solution-based structures, the extension supports a fallback mode using OmniSharp, though this requires manual configuration and installation of additional tooling such as .NET Framework and MSBuild on Windows or Mono with MSBuild on macOS and Linux. The extension's core features include refactoring with code fixes, code navigation through Go To Definition and Find All References, IntelliSense with auto-completion, and formatting and linting capabilities.
The project maintains active engagement with issue reporting through a dedicated support process documented in the repository. Development activity shows consistent attention to both bug fixes and feature improvements across the codebase.
