Editor's note
I put together another mixed lineup here, from teaching tools to deep framework mechanics. The Coding Agent Explorer stands out as a practical way to understand how AI coding agents behave, and the async runtime piece is a good read for anyone tracking where .NET is headed. I also liked the EF Core transactions and caching articles because they focus on everyday reliability and performance.
