Editor's note
I kept this issue intentionally mixed, which is usually where the most useful reading turns up. Meziantou’s piece on disabling HTTP caching in ASP.NET Core APIs is practical advice you can apply immediately, and the EF Core production bugs article is a good reminder that data-layer problems rarely stay small. I also liked the Visual Studio MCP servers preview because it points to how AI tooling is getting wired into everyday .NET work.
