Your AI Agent Says It's Done. Now What? Codex + JetBrains Air in Rider | .NET Day 2026

Agents can write a lot of your code now. You still decide what ships. In this .NET Day 2026 keynote, the JetBrains .NET team shows how JetBrains Air brings your agents into Rider, so you can check their work with the tools you already trust. Writing code got a lot cheaper. Being wrong didn't. What you'll see: Matt Ellis hands a real task to Codex inside Rider, then reviews, tests, and debugs the change before sending feedback back to the agent. Matthias Koch gives an agent the dotTrace skill so it can profile a .NET app and find a real bottleneck. Mehul Harry shows how ReSharper now works in VS Code, Cursor, and other compatible editors.
