Building agentic experiences can feel foreign to developers because the tooling and workflows often don’t look or behave like the IDE-driven, debug-first way we ship software. In this demo-packed session, we’ll show how to create your first Hosted Agent in Microsoft Foundry end to end, from starter code to a working experience. We’ll show everything in the tools developers already trust: your IDE, step-through debugging, and fast local feedback—so the path from idea to running agent is concrete. Next, we’ll show how to add production-grade observability with OpenTelemetry so you can trace agent behavior, spot regressions, and answer “what happened?” with data instead of guesses. Then we’ll show how to connect those signals to continuous deployment so improvements roll out safely and repeatably as you iterate. Along the way, we’ll highlight the key decisions that keep you in control of reliability, cost, and change management as your agent moves toward production. Come see the session to learn how to stay in control while building reliable agentic experiences that delight your end users.
