Microsoft uses Build 2026 to push developers toward fully native Windows apps, not web wrappers, with new tools and a clearer roadmap

Key Points:

• Microsoft is encouraging third-party developers to create native Windows 11 apps using modern frameworks like WinUI 3 to enhance performance and overall user experience as part of the Windows K2 initiative.
• At Build 2026, Microsoft provided sessions and tools, including specialized AI agents like the WinUI agent plugin for GitHub Copilot and Claude Code, to assist developers in building, improving, and migrating apps to native Windows UI frameworks.
• Modernizing apps involves complex tasks beyond rewriting code, such as managing dependencies and data flows, with AI playing a significant role in this process, necessitating powerful hardware capable of supporting AI workloads.
• Microsoft announced the Surface Laptop Ultra, designed for AI agents with up to 128GB RAM and built on the NVIDIA RTX Spark platform, featuring a 20-core Arm CPU and RTX GPU, delivering up to 1 petaflop of AI compute to support demanding development and creative tasks.
• This hardware and software strategy aims to attract developers by providing optimized native app development tools and high-performance devices, reinforcing Microsoft's commitment to advancing the Windows 11 ecosystem.
