⚠️ DEPRECATED
This extension is deprecated due to the latest OmniSharp update, which now provides full support for .NET/C# development across all engines, SDKs, and toolkits in Visual Studio Code.
If you have previously used this plugin—like over 3 million developers — you can safely switch to OmniSharp, which now serves all required features and can be used as a complete replacement.
⚠️ Note: This extension is no longer compatible with the latest versions of Visual Studio Code.
This extension was the world’s first universal C#/.NET support for Visual Studio Code, enabling developers to write C# code in any engine, framework, or toolkit — including .NET Core, Unity, and Godot.
🎉 When Microsoft released the latest OmniSharp version, they personally thanked us for our hard work and assured us that OmniSharp will continue to support C# programming across various tools. Therefore, our plugin is now deprecated, and for similar functionality, simply use the latest .NET and OmniSharp.
This extension is not a compiler itself. It provides:
- ✅ Implementation and proper implementation of .NET Core / .NET Framework
- ✅ Code compilation
- ✅ Access to the latest C# features
- ✅ Built-in code formatter, error detection, and auto-fixing on the fly
Legacy note: C# 5/6/7 support may still be limited in some scenarios.
The primary goal was maximum compatibility across multiple platforms.
For full support of the latest C# features, submit issues or feature requests to the OmniSharp extension repository.
⚙️ Dependencies
This extension does not depend on any third-party extensions (including OmniSharp) and can function as a standalone solution for any C# file.
✨ Features
Provides comprehensive support for C# development across engines, frameworks, and toolkits.
All formatting and tooling features are available through the standard "Format Document" shortcut after opening a C# file.
- ✅ Automatically sorts using directives alphabetically and removes duplicates
- ✅ Fixes indentation for all lines, including wrapped lines
- ✅ Cleans up empty lines, respecting the configured maximum
- ✅ Supports batch formatting through the folder context menu in Explorer
