You can ask Copilot to create workspaces for popular project types with the /createWorkspace slash command. Copilot will first generate a directory structure for your request.
Note: To get access to the Chat view, inline chat, and slash commands (for example /search, /createWorkspace), sign up for the GitHub Copilot chat waitlist (https://github.com/github-copilot/cha...) and install the Pre-Release version of the GitHub Copilot extension.
