Editor's note
I curated a pretty balanced mix today: library news, AI-assisted tooling, and hands-on ASP.NET Core and C# guidance. The MongoDB EF Core 9 update and the Visual Studio Copilot preview stood out because they affect how many teams build and ship right now. I also like the practical pieces on LINQ performance and DI techniques for everyday code.
