C# Dependency Injection vs Service Locator

What is the difference between Dependency Injection and Service Locator in C#?

Dependency Injection (DI) is a design pattern that allows a class to receive its dependencies from an external source, while the Service Locator pattern provides a way to retrieve dependencies from a central registry.

Can you give me an example of how Dependency Injection is implemented in C#?

Sure! In C#, you can use a DI container like Microsoft.Extensions.DependencyInjection to register services and inject them into constructors.

What are the advantages of using Dependency Injection over Service Locator?

DI promotes better testability, reduces coupling, and makes the code easier to manage, while Service Locator can lead to hidden dependencies.

Are there any scenarios where Service Locator might be preferred?

Yes, Service Locator can be useful in legacy systems or when you need to resolve dependencies dynamically at runtime.
