What tool or library have you used for dependency injection in your project?

To implement dependencies in C# projects, libraries that implement the Dependency Injection (DI) pattern are often used. One popular tool is Microsoft.Extensions.DependencyInjection — a built-in container in .NET Core.

Other well-known libraries include:

• Autofac
• Ninject
• Unity

Example of using Microsoft.Extensions.DependencyInjection:

using Microsoft.Extensions.DependencyInjection;

var services = new ServiceCollection();
services.AddTransient<IMyService, MyService>();

var provider = services.BuildServiceProvider();
var service = provider.GetService<IMyService>();

This makes it easy to manage dependencies, improve testability, and maintainability of the code.
