Dependency Injection is a design pattern used to achieve loose coupling between classes.

ASP.NET Core has built-in DI container.

Example:

services.AddScoped<IUserService, UserService>();

Service lifetimes:

  • Transient – new instance every time
  • Scoped – one instance per request
  • Singleton – one instance for application lifetime
