To create a new project using the ActionScript & MXML extension for Visual Studio Code, you must open a folder for your project and create a file named asconfig.json. This configuration file is used to set up your project's compiler options and Adobe AIR packaging options. Until you add the asconfig.json file to your project, code intelligence in .as and .mxml files will not be enabled.

A variety of project types are supported, and the following pages will explain how to set up each type:

• Adobe AIR (Mobile)
• Adobe AIR (Desktop)
• Adobe Flash Player
• Feathers SDK
