What is Dependency Injection in .NET, and how does it improve application design? Can you provide an example of implementing Dependency Injection in an ASP.NET Core application?

Question

Accepted Answer

Dependency Injection in .NET is a design pattern where dependencies are injected into a class rather than created within the class itself.

Dependency Injection helps in achieving loose coupling between classes, making the code more maintainable and testable.
It allows for easier swapping of dependencies, promoting flexibility and scalability.
In ASP.NET Core, Dependency Injection is built into the framework and can be configured in the ConfigureServices method of the Startup class.
For example, you can register a service interface and its implementation in the ConfigureServices method, and then inject it into a controller constructor for use.
