What is dependency injection and life cycle methods

Question

Accepted Answer

Dependency injection is a design pattern that allows objects to be loosely coupled by providing their dependencies externally.

Dependency injection is a way to achieve inversion of control in software development.
It helps in creating loosely coupled and modular code.
In dependency injection, the dependencies of a class are provided externally rather than being created within the class itself.
This allows for easier testing, maintainability, and flexibility in the codebase.
There are different types of dependency injection: constructor injection, property injection, and method injection.
Life cycle methods are used to manage the creation and destruction of objects in a dependency injection container.
Common life cycle methods include: Singleton, Transient, and Scoped.
Singleton creates a single instance of an object throughout the application.
Transient creates a new instance of an object every time it is requested.
Scoped creates a new instance of an object within a specific scope, such as a web request.
