Union types, OAuth, EF Core
This issue spans C# 15 unions, ASP.NET Core OAuth migration, EF Core basics, middleware flow, BackgroundService startup timing, and VS Code modernization.
Jasen's top three picks
- 1 C# Programming Language Guide
c-sharpcorner.com
A broad beginner-oriented C# overview, though it reads more like compiled reference material than a focused tutorial with a distinct angle.
- 2 Introduction to Entity Framework Core — Complete Beginner Guide with Real-World Examples (.NET)
medium.com
A straightforward EF Core starter that should help newcomers connect concepts to practical CRUD-style examples.
- 3 From Request to Response: A middleware journey in .NET
medium.com
A decent walkthrough of the ASP.NET Core middleware pipeline for readers still building intuition about request and response flow.
Editor's note
I like this kind of mixed issue because it mirrors what working .NET developers actually juggle in a week. The C# 15 union types post is the standout language item, and the ASP.NET Core OAuth modernization piece gets into the practical edge cases that usually bite during upgrades. There’s also a useful runtime angle here with BackgroundService startup timing and a nice spread of beginner-friendly C# and EF Core material.
