Step 3: Using GitHub Copilot

With the GitHub Copilot extension installed and your account set up, you’re ready to start using this powerful tool. Here’s how to make the most of it:

  • Accept Suggestions: As you write code in Visual Studio, GitHub Copilot will provide suggestions as you type. These suggestions will appear above your code. To accept a suggestion, simply click on “Accept Solution.”

It’s important to remember that GitHub Copilot is a tool, not an entity responsible for your code. GitHub does not own the suggestions it provides; you remain the sole owner of the code you write with GitHub Copilot’s assistance.

However, it’s crucial to exercise due diligence. Before pushing code to production, make sure to thoroughly test, review, and vet the code. Just as you would with any code you write independently, it’s your responsibility to ensure the quality and correctness of your work.
