GitHub App + Rayfin: Microsoft Build 2026
Microsoft unveiled a new GitHub Copilot desktop app that runs parallel agentic coding sessions and auto-merges PRs.
“When I enable agent merge, Copilot will continuously babysit this PR through CI checks, code review, and merge conflicts.”
At Microsoft Build 2026, Microsoft demoed a new GitHub Copilot desktop app that serves as a home base for development, kicking off parallel agentic coding sessions isolated via Git worktrees and using 'agent merge' to autonomously shepherd PRs through CI, review, and conflict resolution. It signals a shift toward autonomous, multi-session AI coding agents managed from a dedicated client, raising the bar for agentic developer tooling.
