How Dependency Injection Containers Work in C#?

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 ...

What is Abstraction in C#?

The process of defining a class by providing the necessary and essential details of an object to the outside world and hiding the unnecessary things is called abstraction in C#. In C# we can hide the member of a class by using private access modifiers.
Let us understand this with a car example. As we know a car is made of many things, such as the name of the car, the color of the car, gear, breaks, steering, silencer, diesel engine, the battery of the car, engine of the car, etc. Now you want to ride a car. So to ride a car you should know function of Gear,Break and Steering you no need to know engine of the car.so here in case of abstraction we can hide engine details so to do that make engine function private inside class and all require thing what we should know make it's function public.
