What were some of the most surprising things for devs at Build 2026?
Build 2026 debuts agents buildable anywhere (M365, Foundry, GitHub, Copilot Studio) and surfaced directly in M365.
“imagine you don't actually need to think about the front end of an agent”
At Microsoft Build 2026, the headline developer surprises were the ability to build an agent in any surface (M365, Foundry, GitHub, Copilot Studio) and surface it inside M365 where people already work, powered by Work/Web/Foundry/Fabric IQ, plus OpenClaw for Windows gaining enterprise guardrails for always-on background work agents. It matters because it signals Microsoft's push toward ubiquitous, front-end-less agents embedded in existing workflows rather than standalone apps.
