Implementing DI with Native IOC in ASP.NET Core

In this recipe, we will learn in a simple way how to register, resolve, and give a life cycle to an abstraction in ASP.NET Core.

Getting ready

Dependency injection is now native in ASP.NET Core. Importing Microsoft.Extensions.DependencyInjectionin project.json (formerly web.config), and by a using statement in Startup.cs (formerly global.asax), we can use this internal component to manage DI for our application, represented by the IServiceProvider interface.

How to do it...

We will inject the ServiceProducts class by using a constructor in the HomeController of an ASP.NET MVC 6 application:

1. First, we create a class called Product:

2. We then create an interface called IProductService:

3. Next, we create a class called ProductService:

4. Let's use ProductService in our HomeController, creating an instance of ProductService by injecting the ProductService abstraction in the HomeController constructor. ProductService will be available for the whole HomeController...
