Structure

• Client (Consumer): The client or consumer class that depends on other services or components.
• Service (Dependency): The service or dependency that the client needs to perform its tasks.
• Injector (Container): Manages the dependencies and injects them into the client. Contains configuration information about how to create and provide dependencies.

Types of Dependency Injection

Dependency Injection can be implemented in several ways:

• Constructor Injection: Dependencies are provided through the client's constructor. This is the most common and recommended approach as it ensures that dependencies are injected when the object is instantiated.
• Setter Injection (Property Injection): Dependencies are provided through public setter methods or properties of the client after the client object is instantiated. This approach is useful when dependencies are optional or can change after the object is created.
• Method Injection: Dependencies are provided through method parameters when calling methods on the client object. This approach is less common but can be useful in specific scenarios where only certain methods require specific dependencies.

Dependency Injection (DI) is a fundamental concept in modern software development, especially in C# and .NET ecosystems. Let's delve into detailed examples of Dependency Injection in C#, covering various scenarios and implementations.
