C# performance and Azure savings
A varied .NET roundup covering async and GC tuning, C# language tips, Azure cost control, Copilot modes, ASP.NET Core, and SQL advice.
Jasen's top three picks

The Copilot pieces are timely if you’re comparing chat, agent, and IDE-integrated workflows.
Editor's note
