C# practices, EF Core, and Copilot
A mixed .NET roundup on coding habits, EF Core, memory leaks, Minimal APIs, DI lifetimes, Visual Studio Copilot, and SQL Server.
Jasen's top three picks
- 1 Code vs. Experience: What REALLY Makes a Great Developer?
c-sharpcorner.com
A good reminder that experience matters most when code quality meets judgment, not just syntax memorization.
- 2 Types of Classes in C# with Examples | Concrete, Static, Abstract, Sealed, and More
c-sharpcorner.com
A straightforward tour of C# class kinds that still helps newer devs avoid mixing up static, abstract, and sealed.
- 3 Entity Framework Core — Table Per Hierarchy (TPH) Davranışı
medium.com
EF Core TPH behavior is one of those topics that saves real debugging time once inheritance maps get complicated.
Editor's note
I kept this issue varied, with no single theme pulling everything together. The EF Core TPH and query-tags pieces pair nicely with the memory-leak and performance posts if you like practical runtime tuning. I also like the Visual Studio Copilot update because it points at how the editor is changing, not just the app code.
