Build an application with GitHub Copilot agent mode in less than an hour.

People love how GitHub Copilot helps them write code faster and with fewer errors. But what if GitHub could create a full stack application for your job role based on requirements written in natural language. In this exercise, we will prompt GitHub Copilot agent mode to create us a complete application.

• Who is this for: Intermediate developers familiar with GitHub Copilot, basic GitHub, and basic web development
• What you'll learn: We'll introduce GitHub Copilot agent mode and how to use it for application development.
• What you'll build: You'll use GitHub Copilot agent mode to create a fitness application as the gym teacher of a high school.
• How long: This course takes less than one hour to complete.

In this exercise, you will:

1. Start up a preconfigured development environment for making a full stack application.
2. Prompt in GitHub Copilot Chat and select the edit tab and select agent mode from the edit/agent drop down.
3. Try creating the application with GPT-4o.
