  • Modular Dependency Injection in .NET
    2 projects | dev.to | 25 Mar 2024
    When I was building application with .NET Framework I always used libraries like Autofac and SimpleInjector for dependency injection. I really liked to create modules (Packages in SimpleInjector) to achieve higher cohesion and lower coupling in my class libraries. I made a module for every class library in which all dependencies inside of that class library were registered. Why should my web application (for example) know if MyBeautifulService in MyBeautifulClassLibrary should be transient or singleton?
  • Modularize ASP.NET DI configurations using Autofac
    2 projects | dev.to | 14 Nov 2021
    Nevertheless, with the Microsoft.Extensions.DependencyInjection being the new and good default for libraries to provide means for configuration, I want to use these extension methods to setup my dependency injection container of choice, which is Autofac.
  • A Step by Step Guide to ASP.NET Core Dependency Injection
    2 projects | dev.to | 21 Aug 2021
    In the past, we were using libraries and frameworks like Autofac, Castle Windsor or Unity to implement Dependency Injection in our projects but Dependency injection is now part of the ASP.NET Core. All the Framework services like Configuration, Logging, Routing, etc. are now registered in a built-in DI Container and provided to us as services wherever we need them. The basic idea is to register all services (dependencies) when the application starts and then these services will be injected and resolved at runtime.

  • Does anybody has a recommended resource about Dependency Injection?

    My favorite DI container is LightInject. Very fast and has all the features that I need. Other good DI containers are Grace and SimpleInjector, IMO.
