Jasen's top three picks

- 2 How try-catch Works Internally in .NET – A Beginner’s Breakdown
Medium
This is a useful internals refresher that explains try-catch behavior without assuming deep runtime knowledge.
- 3 8 .NET Code Review Tips to Make Your Team Love You

Solid practical advice for keeping code reviews helpful, consistent, and less personal.
Editor's note
I pulled together a deliberately mixed lineup this time, from performance and modernization to ASP.NET Core and security. The .NET 10 performance piece and the June 2025 update advisory are the standouts for anyone tracking what changes now matter most. The rest covers practical day-to-day work, including API design, observability, and refactoring patterns.
