Editor's note
I pulled a deliberately mixed lineup this time: old-school Web Forms, modern ASP.NET Core, and a few architecture pieces that spark good debates. The CQRS ≠ MediatR piece is a nice reminder to keep patterns and tools separate, and the source-generated contracts article is a practical warning for .NET 9 teams. I also liked the Azure AI agent and Swagger posts for readers building real APIs right now.
