Supercharged profiling: Finding performance bugs with agents | DEM300

Modern performance problems are harder than ever to diagnose: distributed systems, async code, and massive data make traditional profiling insufficient. In this demo-driven session, watch how Visual Studio combines advanced diagnostics with AI-powered agents to surface bottlenecks, explain root causes, and guide fixes faster than ever. From CPU and memory issues to “it only fails in production” bugs, you’ll see how profiling evolves in an agentic world. Seating for this session is first-come, first-served. Add it to your schedule to plan your day and arrive early to secure a spot.
