Microsoft Build 2026 announcements for Visual Studio focus on deeper AI integration via GitHub Copilot agents that participate in debugging, profiling, and testing workflows. Key highlights include: pre-build error checking to avoid wasted build cycles, AI-assisted merge conflict resolution, a modernization agent to migrate Web Forms apps to Blazor and add .NET Aspire support, context-aware auto-applied skills, bring-your-own-key/model (BYOK) support for flexible AI model usage, and a unified GitHub Copilot SDK as the underlying foundation for all AI features.
