EF Core Performance, AI Apps, and API Testing

Covers EF Core query tuning, N+1 pitfalls, HttpClient failures, ASP.NET Core testing, Clean Architecture, RabbitMQ, and Semantic Kernel builds.

Jasen's top three picks

  1. 1
    How to Simplify ASP.NET Core API Testing

    medium.com

    Useful if your test setup keeps sprawling; I like anything that reduces friction around ASP.NET Core integration testing.

  2. 2
    Building a Vehicle Rental Management System in C# Using Entity Framework Core

    c-sharpcorner.com

    More starter-app oriented, but still a decent walk through EF Core in a business-style console application.

  3. 3
    Scalability in .NET Backend Systems: Design Decisions That Matter Before Infrastructure

    medium.com

    A good reminder that scalability problems usually start in code and data access patterns before they start in Kubernetes.

Editor's note

I kept this one nicely mixed on purpose: practical API testing, a cluster of EF Core performance pieces, and several real-world AI app builds. The HttpClient production warning is the kind of lesson teams usually learn the hard way, and Anton’s take on EF Core in Clean Architecture is worth reading because it cuts through a lot of ceremony.
