C#/.NET Compiler + AIO Toolkit installs statistics

⚠️ 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.

🚀 C#/.NET Compiler + AIO Toolkit for 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
