Editor's note
I kept this issue deliberately mixed: security, tooling, platform updates, and hands-on app guidance all showed up. The AutoMapper vulnerability note is the kind of reminder I like to surface quickly, while the EF Core 10 seeding and test sharding pieces are the sort of practical reads that save teams time.
