C# fundamentals, EF Core, and Azure messaging
This issue covers C# language basics, EF Core guidance, Azure Service Bus, .NET 9, observability, performance, and native Windows apps.
Jasen's top three picks
- 1 What Are Assemblies and DLLs in C#? A Visual Studio Guide for Beginners
medium.com
A solid beginner-friendly C# opener: assemblies, DLLs, and how Visual Studio helps you see what’s actually being built.
- 2 Understanding Task.FromCanceled
medium.com
Task.FromCanceled is a deceptively small API with real impact on async correctness and cancellation handling.
- 3 Clean Architecture with Modular Monolith and Vertical Slice
medium.com
The modular monolith and vertical slice piece is a useful architecture combo for teams trying to stay organized without over-splitting.
Editor's note
I put together a wide mix today: beginner-friendly C# pieces, architecture discussions, and practical data access posts. The Task.FromCanceled write-up and the EF Core Unit of Work article stood out because they both tackle common mistakes developers make in day-to-day code. I also included the .NET 9 upgrade discussion and the monitoring/logging piece for teams thinking about platform choices and reliability.
