Editor's note
I curated a deliberately mixed issue today, with everything from EF Core modeling and change-tracking pitfalls to Aspire observability and Visual Studio 2026 Insiders. The .NET Security Group announcement is worth a close read, and the memory-leak troubleshooting piece is a practical reminder that production diagnostics still matter.
