Editor's note
I pulled together a very mixed issue this time: practical ASP.NET Core guidance, security, client-side UI, and a few architecture and AI pieces. The middleware and SignalR articles are solid refreshers, while the Aspire Dashboard and EF Core scaffold automation posts are the kind of workflow improvements that pay off quickly.
