Part of: ASP.NET Core: a working guide for .NET developers

Topics: ASP.NET Core .NET Aspire Azure C# Docker FluentValidation GitHub Copilot gRPC Semantic Kernel WPF

Editor's note

I kept this issue intentionally mixed, which is usually where the best surprises show up. The Semantic Kernel multi-agent walkthrough is timely because it gets concrete about orchestration instead of hand-waving, and Tim Deschryver’s Aspire BFF post is a practical look at moving a secure app toward containers. I also liked the FluentValidation gRPC package write-up because dependency-version pain is the kind of problem working teams actually hit.
