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 namespace in c# ?


Namespaces in C# are used to organize classes.To access the class of a namespace, we need to use namespacename.classname. namespace is designed for providing a way to keep one set of names separate from another. The class names declared in one namespace does not conflict with the same class names declared in another. To define a namespace we need to use "namespace". eg.
  namespace NamespaceName
 { 
     class className
     {
     }
 }

 namespace WpfWorldNamespace
 { 
     class WpfWorld
     {
     }

 }
if we want to use WpfWorld class in another class then we have to add WpfWorldNamespace to that class by using Keyword.

 using WpfWorldNamespace;
 namespace ExNamespace
 { 
     class Ex
     {
       var objWpfWorld = new WpfWorld();
     }

 }
