 A Dependency Injection (DI) Container provides functionality and automates many of the tasks involved in Object Composition, Interception, and Lifetime Management. It's an engine that resolves and manages object graphs. These DI Containers depend on the static information compiled into all classes. Then using reflection they can analyze the requested class and figure out which Dependencies are required.

 Creating a dependency injection container required three basic components.
 
- * Object Composition - A object composition defining a set of objects to create and couple.
- * Registering Services - Define an instance of the ServiceCollection and register the object composition with a specific service lifetime.
- * Service Provider - Creating a service provider to retrieve the object.
