A Microsoft Build session from the Visual Studio team showcasing GitHub Copilot's agentic capabilities inside Visual Studio. Demos include a debugger agent that reproduces a crash via a failing unit test and fixes an off-by-one error, and a profiler agent that collects instrumentation traces during CI test runs, identifies hot paths, applies code optimizations, and re-profiles to validate improvements — nearly doubling performance of a large file decode operation. The session also covers the roadmap: app modernization from WebForms to Blazor, automatic agent skill injection based on project type, AI-assisted merge conflict resolution, migration to the shared GitHub Copilot CLI SDK for feature parity with VS Code, and support for any model including local/on-prem models with enterprise governance controls.
