How to Implement Dependency Injection (DI) in .net Core Console Application

In this post on my blog, I will demonstrate how to use Dependency Injection in a.NET console application.

What is meant by the term “Dependency Injection”?

According to Wikipedia,

Dependency injection" is a design pattern used in software engineering, and it refers to the process by which an object or function receives additional objects or functions that it depends on. Dependency injection is a sort of inversion of control that seeks to separate the concerns of constructing objects and using them, ultimately resulting in programmes that are loosely connected with one another.

What are the benefits of utilizing DI?

DI offers a number of benefits, but the most significant are the following:

  • Removed the tight coupling between classes and the dependencies they had.
  • During testing, it is simple to switch out the actual implementation with a mock or sham version.
