Part of: ASP.NET Core: a working guide for .NET developers, EF Core: a working guide for .NET developers, Performance: a working guide for .NET developers
Editor's note
I put together another deliberately mixed issue today, with plenty for both app developers and tooling-minded folks. The CQRS dispatcher piece stands out because it tackles the post-MediatR-commercial shift with concrete .NET 10 and AOT considerations, and the EF Core change tracker article is the kind of practical debugging guidance teams actually need in production. I also liked the Visual Studio floating windows update since small IDE workflow improvements can add up fast on multi-monitor setups.
