Inversion of Control through Dependency Injection
Inversion of Control (IoC) is a programming principle where the control over certain aspects of a program’s flow is handed over from the main code to a framework or a container. In simple terms, instead of a component being responsible for managing its dependencies and life cycle, these responsibilities are inverted or delegated to an external controller. This approach is particularly useful for creating modular and flexible systems.
In a typical software design without IoC, a class that requires certain functionalities from other classes would create or manage these dependent objects within itself. With IoC, this creation and management is handled by an external component, hence inverting the control.
IoC can be achieved through various methods such as DI, Factory Pattern, Service Locator, and more. Among these, DI is the most commonly used method in the context of MVVM.
