Do we need dependency injection in MVC, how does it help?

Question

Hi,

What is the advantage of using dependency injection.

I have to work on a project using constructor dependency injection.

The service interface is passed to controller constructor.

Even the service has constructor.

How does this work?

I cannot find what initializes the service constructor.

Thanks,
Regards.

If you look at the Startup.c, you'll see the the Services for the objects I will be DI from the Models folder into controllers and Service Layer objects will be DI into Model objects, all based on what was established for the IoC in Startup.cs
