Dependency Injection (DI) containers, such as Unity or DryIoc, help manage the creation and lifetime of object dependencies in C#. They facilitate the Inversion of Control (IoC) principle, allowing you to focus on writing clean, maintainable code without worrying about the complexities of instantiating dependencies manually. How DI Containers Work? Registration:  You define which concrete classes should be used to fulfill specific interface contracts. This allows the DI container to know what to instantiate when a class requests a particular dependency. Resolution:  When an instance of a class is requested, the DI container looks at the registered services, resolves the dependencies, and creates the object with the required dependencies injected. Lifetime Management:  The container manages the lifecycle of the dependencies. You can specify whether instances should be singleton (one instance for the entire application), transient (a new instance each time), or scoped (one ...

  IoC Container IoC Container is a framework for implementing automatic dependency injection . before I explain IoC Container first lets know what is  dependency injection Dependency Injection It is a design pattern used to implement IoC. It allows the creation of dependent objects outside of a class and provides those objects to a class through different ways.  The Dependency Injection pattern involves three things which are client, service and the injector so, there will be  three  types of classes  involves in this process . Client Class : The client class is a class which depends on the service class. Service Class : The service class is a class that provides service to the client class. Injector Class : The injector class injects the service class object into the client class. The injector class injects dependencies in three ways: through a constructor, or through a property, or through a method. so, there are three types of Dependenc...
