What is Dependency Injection and available Containers(IOC)

Posted on Updated on

What is Dependency Injection (DI) Design Pattern ?
Dependency injection (DI) design pattern is based on separating component behavior from dependency resolution without object intervention.

This pattern is a particular implementation of Inversion of Control, where the consumer object receives his dependencies inside constructor properties or arguments.

DI requires a framework component behind to deal with class constructor.

The basic pattern for integrating Autofac into your application is:

•Structure your app with inversion of control (IoC) in mind.
•Add Autofac references.
•At application startup…
•Create a ContainerBuilder.
•Register components.
•Build the container and store it for later use.
•During application execution…
•Create a lifetime scope from the container.
•Use the lifetime scope to resolve instances of the components.

The Unity Application Block (Unity) is a lightweight extensible dependency injection container with support for constructor, property, and method call injection.

Unity addresses the issues faced by developers engaged in component-based software engineering. Modern business applications consist of custom business objects and components that perform specific or generic tasks within the application, in addition to components that individually address cross cutting concerns such as logging, authentication, authorization, caching, and exception handling.
