• Stop using trivial Guard Clauses! Try this instead – Some interesting and good advice by Derek Comartin. Instead of simply adding guard classes as a thing you do because that’s the way you’re supposed to do it, stop and consider those times when your guard classes might be unnecessary, and what to do instead.
• Layered security for DotNet Core APIs – More security by Ted Spence. This time, it’s how to think about securing your apps layer by layer, rather than by thinking in terms of logins and accessible assets only.
• Book:  Parallel Programming and Concurrency with C# 10 and .NET 6 – Alvin Ashcraft wrote an entire book on some hefty topics, particularly useful for those working on high traffic websites and apps.

Here’s a nice Twitter thread on some helpful APIs.
