• Blog Modern .NET Backend Roadmap — Part 1: Clean Architecture

  Start the roadmap with a clean-architecture solution on .NET 10: domain entities with behavior, application-layer ports, infrastructure adapters, and a thin API — dependencies enforced by the compiler

• Blog How to Implement Dependency Injection in .NET Core

  Learn dependency injection in .NET with the built-in IoC container — register services in Program.cs, inject them through constructors, choose lifetimes, and swap implementations with one line.

• Blog Read appsettings.json in a .NET Class Library with Dependency Injection

  The options pattern done right: the host owns configuration sources, the library declares typed settings, and DI carries one to the other — with validation at startup.

• Blog .NET Dependency Injection Object Lifetimes

  Transient, scoped, and singleton lifetimes demonstrated with GUIDs — what each means, why DbContext is scoped, and the captive-dependency trap that leaks state across requests.
