// From 'It works on my machine' to 'It was written by a machine' - GitHub Codespaces & Copilot

Setting up a development environment—installing the right SDK versions, extensions, and tools—wastes hours and causes 'works on my machine' problems. This episode shows how VS Code's Remote Containers extension and GitHub Codespaces solve this with containerised, reproducible dev environments defined in a devcontainer.json file. See a live demo of editing cloudwithchris.com entirely in a browser-based Codespace.

Chris and Matt deploy the World Events Engine to Azure Container Apps — encountering and fixing a real-world GitHub Actions deployment bug caused by parallel runs generating duplicate container names. The episode covers Dapr storage queue bindings, service invocation between microservices, random bar-type modifier logic, and a viewer-prompted conversation about using GitHub Codespaces to standardise the development environment.

The series officially rebrands from ToolUp Tuesday to ToolUp Days, giving Chris and Matt the flexibility to keep a consistent cadence. This episode focuses on rethinking the game's data model — simplifying the player state object, introducing a BarType enum, and scaffolding both a player creation API and a bar management controller, with GitHub Copilot generating much of the boilerplate in real time.
