SQL, SignalR, and .NET 10 performance
A wide mix of .NET reads: SQL fundamentals, SignalR with Wolverine, Azure observability, caching, validation, and .NET 10 collection speedups.
Jasen's top three picks
- 1 How Learning SQL Can Open Doors in the Age of Data
trevoirwilliams.com
A useful reminder that SQL still opens doors, especially if you want to understand data-driven systems instead of just consuming them.
- 2 Using SignalR with Wolverine 5.0
jeremydmiller.com
Wolverine + SignalR is a nice combo for real-time apps; this one is for people building messaging-heavy systems.
- 3 Mastering Mailbox Cleanup and Holds in Exchange Online

The .NET 10 foreach benchmarks are the kind of thing performance-minded devs should pay attention to before they tune hot paths.
Editor's note
I kept this issue intentionally mixed, with practical app-building posts alongside performance and platform pieces. The .NET 10 foreach benchmark and the SignalR + Wolverine write-up stood out because they point to real-world throughput and messaging work. I also liked the observability item for AI agents, since it ties Aspire, Application Insights, and OpenTelemetry into something teams can use today.
