The C# Dev Kit extension, unveiled June 6, brings an improved “editor-first” C# development experience to these operating platforms, according to a Microsoft blog post. C# Dev Kit borrows concepts from the Visual Studio IDE, with the goal of providing a more productive and reliable experience for tasks such as editing a C# file, learning the language, or debugging a back-end API.
The C# Dev Kit extension builds on C# language capabilities provided by the VS Code C# extension, which has been updated to use a new open source Language Server Protocol host, providing a tools environment to easily integrate new experiences into C# for VS Code. Microsoft will continue to maintain the C# extension independently of the C# Dev Kit.
Specific capabilities of C# Dev Kit include:
- C# project and solution management through an integrated solution explorer.
- A native testing environment to run and debug tests via the Test Explorer. Tests in XUnit, NUnit, MSTest, and bUnit will be discovered more easily for quick executions.
- A Roslyn-powered language service for C# language features such as code navigation, semantic awareness, and refactoring.
- AI-assisted development including whole line completions.
The C# Dev Kit automatically installs the C# extension and the IntelliCode for C# DevKit extension, which provides AI-assisted development features. This extension offers predictions of as much as a whole line of code, along with ranking methods and properties in the IntelliSense list for C# Dev Kit users. .NET 6 is required for the IntelliCode extension.
Microsoft asks developers to share their feedback regarding the C# Dev Kit through VS Code’s Help > Report Issue capability.
