Editor's note
I curated a broad mix this issue, with no single theme—just the most useful reads I found across architecture, runtime, and web stack topics. The ASP.NET Core 9 piece stands out for practical web-app changes, and the DDD/CQRS template plus strongly typed IDs articles are useful if you’re tightening up domain models.
