Modernize your .NET apps for Windows Arm64 with GitHub Copilot

The GitHub Copilot upgrade agent now supports migrating .NET applications from Windows x64 or x86 to Windows Arm64. It assesses your projects, flags blockers like architecture-tied build settings and native dependencies without Arm64 binaries, then builds a migration plan. The agent updates code, dependencies, and project configuration, and builds the migrated app for Arm64, running tests when matching hardware or CI runners are available. It focuses on portability and correctness, not Arm64 performance tuning. To start, install GitHub Copilot upgrade, pick the .NET Arm64 migration scenario, and review its plan before letting it make changes.

Agents aren’t humans (but they kinda are)

AI agents act for millions, but servers see intermediaries that strip user visibility. This post defines the problem space and introduces a collaborative approach to safely identifying, allowing, and managing this automated traffic.

Microsoft.UI.Reactor: a C#-first way to build WinUI apps

Microsoft.UI.Reactor là một framework C# để phát triển ứng dụng WinUI, ra mắt tại Microsoft Build 2026. Framework này giải quyết vấn đề hiệu năng khi render UI bằng cách implement virtual DOM pattern tương tự React. Thử nghiệm cho thấy UI.Render cải thiện 30% tốc độ so với WinUI truyền thống. Điều đáng học hỏi là cách tiếp cận hybrid này kết hợp ưu điểm của C# với pattern từ frontend JavaScript. Bạn nên đọc bài gốc nếu đang tìm cách tối ưu hóa hiệu năng cho ứng dụng WinUI của mình.
