What are the best practices for dependency injection in ASP.NET Core?

What are the best practices for dependency injection in ASP.NET Core?

Some best practices include using constructor injection, keeping services stateless, and registering services with the appropriate lifetime.

Can you explain the different service lifetimes in ASP.NET Core?

Sure! There are three main lifetimes: Transient, Scoped, and Singleton. Transient services are created each time they're requested, Scoped services are created once per request, and Singleton services are created once and shared throughout the application's lifetime.

How do I register a service in the Startup class?

You can register a service in the ConfigureServices method of the Startup class using services.AddTransient, services.AddScoped, or services.AddSingleton depending on the desired lifetime.

What are some common pitfalls to avoid with dependency injection?

Common pitfalls include injecting too many dependencies into a single class, not using interfaces, and failing to manage service lifetimes properly.
