Web API, EF Core, CQRS and .NET 9 benchmarking
This issue covers API design, security, EF Core tuning, concurrency, migration, and .NET 9 benchmarking for working developers.
Jasen's top three picks
- 1 Building an ASP.NET Web API Controller
c-sharpcorner.com
A concrete controller walkthrough with SQL and header validation — useful if you like seeing API plumbing end to end.
- 2 ⚡ CUE + OpenAPI: Declarative API Design for Scalable, Reliable .NET Services
blog.yaseerarafat.com
A contract-first API piece that pairs CUE with OpenAPI; good fodder for teams trying to keep specs and code aligned.
- 3 Application Domain In C#
medium.com
A reminder that ApplicationDomain still comes up in legacy and plugin-style .NET discussions.
Editor's note
I put together a deliberately mixed lineup today: practical Web API work, data-access tuning, and a few architecture pieces. The EF Core performance article and the .NET 9 benchmarking comparison are especially useful if you’re looking for real-world tradeoffs, not just patterns. I also liked the CUE + OpenAPI piece for its contract-first angle and the JWT/OAuth article for keeping API security grounded.
