Unity Development with VS Code

Visual Studio Code can be a great companion to Unity for editing and debugging C# files. All of the C# features are supported and more. In the screen below, you can see code colorization, bracket matching, IntelliSense, CodeLens and that's just the start.

Unity Example

Read on to find out how to configure Unity and your project to get the best possible experience.


From Using .NET Core in Visual Studio Code:

  1. Install the .NET Core SDK, which includes the Runtime and the dotnet command.

  2. [Windows only] Logout or restart Windows to allow changes to %PATH% to take effect.

  3. [macOS only] To avoid seeing "Some projects have trouble loading. Please review the output for more details", make sure to install the latest stable Mono release.

    Note: This version of Mono, which is installed into your system, will not interfere with the version of MonoDevelop that is installed by Unity.

  4. Install the C# extension from the VS Code Marketplace.

Setup VS Code as Unity Script Editor

Open up Unity Preferences, External Tools, then browse for the Visual Studio Code executable as External Script Editor.

Unity Preferences

The Visual Studio Code executable can be found at /Applications/Visual Studio Code.app on macOS, %localappdata%\Programs\Microsoft VS Code\Code.exe on Windows by default.

Unity has built-in support for opening scripts in Visual Studio Code as an external script editor on Windows and macOS. Unity will detect when Visual Studio Code is selected as an external script editor and pass the correct arguments to it when opening scripts from Unity. Unity will also set up a default .vscode/settings.json with file excludes, if it does not already exist (from Unity 5.5 Release notes).

Unity version 2019.2 or above

Since 2019.2, it is required to use the Visual Studio Code editor package. The built-in support for opening scripts from Unity and getting csproj and sln files generated has been removed.

Editing Evolved

With the solution file selected, you are now ready to start editing with VS Code. Here is a list of some of the things you can expect:

  • Syntax Highlighting
  • Bracket matching
  • IntelliSense
  • Snippets
  • CodeLens
  • Peek
  • Go-to Definition
  • Code Actions/Lightbulbs
  • Go to symbol
  • Hover

Two topics that will help you are Basic Editing and C#. In the image below, you can see VS Code showing hover context, peeking references and more.

Unity Extensions

The community is continually developing more and more valuable extensions for Unity. Here are some popular extensions that you might find useful. You can search for more extensions in the VS Code Extension Marketplace.

The extensions shown above are dynamically queried. Select an extension tile above to read the description and reviews to decide which extension is best for you. See more in the Marketplace.

Enabling code completion (For recent versions of Unity)

If you are installing VS Code for the first time, you might be missing targeting packs required for Unity's code-completion (IntelliSense) in VS Code.

Targeting pack download links:


  1. Stop VS Code or Unity running.
  2. Download and install the targeting pack for your targeted framework version / preferred version from one of the above links.
  3. Start Unity.
  4. Create and/or open an existing script in VS Code, through Unity, and you should now see code completions.

Common questions

I don't have IntelliSense

You need to ensure that your solution is open in VS Code (not just a single file). Open the folder with your solution and you usually will not need to do anything else. If for some reason VS Code has not selected the right solution context, you can change the selected project by clicking on the OmniSharp flame icon on the status bar.

OmniSharp Flame on the Status Bar

Choose the -CSharp version of the solution file and VS Code will light up.

How can I change the file exclusions?

Unity creates a number of additional files that can clutter your workspace in VS Code. You can easily hide these so that you can focus on the files you actually want to edit.

To do this, add the following JSON to your workspace settings.

    // Configure glob patterns for excluding files and folders.
    "files.exclude": {
        "**/.git": true,
        "**/.DS_Store": true,
        "**/*.meta": true,
        "**/*.*.meta": true,
        "**/*.unity": true,
        "**/*.unityproj": true,
        "**/*.mat": true,
        "**/*.fbx": true,
        "**/*.FBX": true,
        "**/*.tga": true,
        "**/*.cubemap": true,
        "**/*.prefab": true,
        "**/Library": true,
        "**/ProjectSettings": true,
        "**/Temp": true

As you can see below this will clean things up a lot...
