Using .NET in Visual Studio Code

.NET provides a fast and modular platform for creating many different types of applications that run on Windows, Linux, and macOS. Use Visual Studio Code with the C# and F# extensions to get a powerful editing experience with C# IntelliSense, F# IntelliSense (smart code completion), and debugging.

Setting up VS Code for .NET development

.NET Coding Pack

To help you set up quickly, you can install the .NET Coding Pack, which includes VS Code, the .NET Software Development Kit, and essential .NET extensions. The Coding Pack can be used as a clean installation, or to update or repair an existing development environment.

Install the .NET Coding Pack - Windows

Install the .NET Coding Pack - macOS

Note: The .NET Coding Pack is only available for Windows and macOS. For other operating systems, you will need to manually install the .NET SDK, VS Code, and .NET extensions.
