The Code Brew's Weekly Newsletter - Week 1

Welcome to the first issue of The Code Brew's Weekly! ☕ This edition is packed with insights for developers. We're kicking things off with a deep dive into the .NET ecosystem, covering everything from a new EF Core query visualizer and the nuances of collection expressions to a look at .NET MAUI with an MVU approach. The other major theme this week is AI, with fantastic articles on building your own coding agent, practical guides for GitHub Copilot, and a look at how Cloudflare and Netflix are leveraging machine learning. Beyond that, we've got handy tips on Git Worktree, creative CSS tricks, and top discussions from Hacker News and Reddit on career burnout, the future of C#, and why CORS is so important.
