Editor's note
I kept this one deliberately broad, which is usually when the most useful combinations show up. The passkey authentication walkthrough is worth your time if you’re hardening sign-in flows, and the .sln to .slnx piece is a practical look at tooling evolution that will affect day-to-day .NET work. I also liked the host process deep dive and the webhook delivery article because both focus on the kinds of operational details that bite real systems.
