Overview
GitHub Copilot is only as good as the way you drive it. This session showed .NET developers how to move past autocomplete and use Copilot as a genuine pair programmer across a real C# codebase.
What we covered
- Prompting that works — comments, function signatures, and context files that steer Copilot.
- Tests first — generating xUnit tests and using them to pin down behaviour.
- Refactoring safely — extracting methods, adding null-handling, and modernising old code.
- Copilot Chat — explaining unfamiliar code, fixing exceptions, and writing docs.
- When to say no — reviewing suggestions critically and avoiding subtle bugs.
