What is IoC and DI in Spring with example?

DI is the process of providing the dependencies and IoC is the end result of DI. (Note: DI is not the only way to achieve IoC. There are other ways as well.) By DI, the responsibility of creating objects is shifted from our application code to the Spring container; this phenomenon is called IoC.

What is IoC in MVC C#?
