Letting Codex build a .NET + PostgreSQL app
Jul 05, 2025
I’ve been poking at OpenAI Codex for a while, and it’s starting to feel like pairing with a junior dev who never sleeps.
In this new video I let Codex build a small whisky-tasting app on top of .NET + PostgreSQL — inside a Codex environment that doesn’t even ship with .NET out of the box. Along the way we hit the classic “binary files are not supported” problem and fix it with a simple git patch workflow.

If you’re curious how AI agents behave on a real codebase (and not just tiny demos), this is a nice, honest run-through.
