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 ...

Why we should use xaml in Wpf ?

The specific advantage that XAML brings to WPF is that XAML is a completely declarative language, allowing the developer (or designer) to describe the behavior and integration of components without the use of procedural programming. Although it is rare that an entire application will be built completely in XAML, the introduction of XAML allows application designers to more effectively contribute to the application development cycle. Using XAML to develop user interfaces also allows for separation of model and view, which is considered a good architectural principle. 

"XAML is used when we have two systems which are in heterogeneous in nature.so WPF internal representation is XAML.so if we create the UI in XAML than it can be render on windows application,web application inside browser."
