Build 2026 marked a turning point: Microsoft repositioned its entire developer platform around AI agents. Copilot is no longer a feature — it is the architecture.
Azure AI Agent Service, Copilot Studio, and the new Agent Framework are all built on the same principle: the developer experience should start with the agent, not the application.
This is a fundamental shift from "build an app and add AI" to "build an agent and let it use your app." The developer playbook is being rewritten. Teams that understand this shift early will have a structural advantage.
