Getting Started with C# in VS Code

This getting started guide introduces you to C# and .NET for Visual Studio Code through the following tasks:

  1. Installing and setting up your VS Code environment for C#.
  2. Writing and running a simple "Hello World" application using C#.
  3. Introduce you to other learning resources for C# in VS Code.

Keep in mind, that this guide won't teach you C#. Instead, it teaches you how to get set up for C# development in VS Code. If you're looking for resources to learn C#, check out our C# curriculum.

Installing VS Code and extensions

  1. If you haven't already done so, install VS Code.
  2. Next, install C# Dev Kit from the Visual Studio Marketplace. For additional details on installing extensions, read Extension Marketplace. The C# extension is called C# Dev Kit and it's published by Microsoft.

Note: C# Dev Kit supports cloud native development. To do cross-platform mobile and desktop development, you can use C# Dev Kit with the .NET MAUI extension. Learn how to get set up with .NET MAUI in VS Code.

Upon installation, C# Dev Kit launches an extension walkthrough. You can follow the steps of this walkthrough to learn more about the features of the C# extension. You can also use this walkthrough to install the latest .NET SDK. Reopen the walkthrough at any time by opening the Command Palette (⇧⌘P (Windows, Linux Ctrl+Shift+P)) and selecting Welcome: Open Walkthrough. Here, select Get Started with C# Dev Kit.

C# Dev Kit introductory walkthrough

Note: You are required to sign in to a Visual Studio subscription to use C# Dev Kit. Check out the Signing in to C# Dev Kit documentation to learn more.

In the walkthrough, select Set up your environment and select Install .NET SDK. This will open a window next to the walkthrough with a button to install the latest version of the .NET SDK. Select the Install button, which will trigger a download and an install of the .NET SDK. Follow the on-screen instructions to complete this process.

Install .NET SDK

Create a Hello World app

To get started, go to the Explorer view and select Create .NET Project. Alternatively, you can bring up the Command Palette using ⇧⌘P (Windows, Linux Ctrl+Shift+P) and then type ".NET" and find and select the .NET: New Project command.

  1. After selecting the command, you'll need to choose the project template. Choose Console app.
  2. To run your app, select Run > Run without Debugging in the upper menu, or use the ⌃F5 (Windows, Linux Ctrl+F5) keyboard shortcut. To learn more about debugging your C# project, read the debugging documentation.
