Editor's note
I curated a pretty mixed issue today, with security, performance, data access, and tooling all in the same lineup. The JWT role-based auth piece is practical for teams tightening API access, and the EF Core bulk operations article tackles a pain point many of us hit at scale. I also liked the Visual Studio AI roadmap update because it gives a clearer view of where the editor experience is headed.
