Authentication, async, and API design
A varied .NET roundup covering auth flows, password hashing, async/await behavior, API and MVC choices, SQL myths, and practical patterns.

c-sharpcorner.com
Copilot Studio Kit is the AI-adjacent pick here—useful if you’re building around Microsoft’s ecosystem.
- 2 Session vs JWT vs OAuth vs SSO Explained with Real C#.NET Examples
medium.com
JWT, OAuth, SSO, and password storage make this a practical security block, not just theory.
- 3 Storing Passwords Securely in .NET: A Beginner-Friendly Guide to Hashing and Salting

The async/deadlock and SynchronizationContext pieces are worth a careful read if you ship UI or service code.
Editor's note
I kept this issue deliberately mixed: security, runtime behavior, architecture, and a little AI. Damien Bod’s OpenID Connect error handling piece is a solid real-world one for anyone wiring up sign-in, and the async/await deadlock article is a good reminder that the details still matter. The Microsoft Build recap and RAG chatbot post round out the issue with timely platform updates and applied AI.
