Editor's note
I kept this issue deliberately mixed, with performance, tooling, UI, and AI pieces side by side. The Span and Memory article is a good practical refresher, and the Visual Studio 17.13 profiling update stands out for everyday debugging work. I also liked the EF Core and SignalR posts because they tackle real-world app bottlenecks and realtime patterns.
