Greenfield Development with Copilot and VS Code

John Miller

This instructor-led workshop demonstrates how GitHub Copilot and VS Code's AI capabilities can accelerate greenfield development by building new applications with sustainable practices from the start. Through demonstrations, participants will learn to use custom chatmodes (Code Reviewer, Security Analyst, Architect, Test Engineer) and AI-powered workflows to guide requirements gathering, planning, and vertical slice implementation. The session covers generating detailed requirements, comparing outputs from multiple AI models for reliability, and delivering working increments quickly while maintaining quality. By day's end, attendees will understand how to launch greenfield projects using AI-assisted development practices that ensure adaptability and speed without sacrificing code quality.

This event took place on Wednesday, December 3, 2025.

Presenter: John M. Miller

When: Wednesday, December 3, 2025 8:00am Central Time (CT)

Duration: 7 hours (approximately, includes an hour for lunch)

This one‑day workshop explores how GitHub Copilot and VS Code's AI-assisted development environment can accelerate greenfield development, starting from scratch and building new applications with sustainable practices from the outset. Attendees will work in interactive, attendee‑led sessions to design instruction files, prompt files, and custom chatmodes that guide GitHub Copilot and VS Code through requirements gathering, planning, and implementation.

The workshop emphasizes vertical slicing as a strategy to speed development and improve feedback loops. Participants will:

  • Generate detailed requirements and implementation plans using GitHub Copilot's code generation and VS Code's integrated AI capabilities.
    -Use custom chatmodes (e.g., Code Reviewer, Security Analyst, Architect, Test Engineer) within VS Code to guide design and coding decisions.
  • Implement features slice‑by‑slice using Copilot's intelligent code suggestions, validating business rules and technical choices along the way.
  • Compare outputs from multiple AI models to understand bias and improve reliability.

By the end of the day, attendees will have experienced how to launch a greenfield project from scratch using GitHub Copilot and VS Code's AI‑assisted workflows, delivering working increments quickly while maintaining quality and adaptability through intelligent development practices.
