Editor's note
I pulled together a genuinely mixed issue this time: language, cloud, web API, data, and tooling all show up. The C# 13 extended params piece and the Azure resilient autoscaling article are both worth a close read if you like practical changes, not just headlines. I also flagged the Copilot review and refactoring posts because they capture where AI assistance is helping—and where it still misses the mark.
