Configure VS Code

If you are new to VS Code or to developing C# applications with VS Code take the time to follow the next steps.

1. Open VS Code
2. If this is not a new installation then try to update it. Press F1 and type Code: Check for Updates... and select it. A notification will tell you if an update is available.
3. Configure VS Code to start from the command-line using the code command. This can be configured by following these instructions.
4. Install the Uno Platform extension. Press F1 and type Extensions: Install Extensions, search the marketplace for Uno Platform and click the Install button.

OmniSharp Legacy Mode

Starting Uno Platform extension version 0.12, running in VS Code automatically uses the C# Dev Kit extension ms-dotnettools.csdevkit.

If you are using GitPod, any Open VSX environment or earlier versions of the Uno Platform extension, you will be automatically using the C# extension ms-dotnettools.csharp with OmniSharp enabled.

To switch between C# Dev Kit and OmniSharp:

• Switch to C# Dev Kit Mode
• Switch to OmniSharp Mode
