Configuración inyector DI
Hay que registrar los servicios en un startup.cs. Hay 3 tipos:
- transient: dependencies are created each time they’re called.
- scoped: lives while request is available.
- singleton: only created once for whole project.
public class Startup
{
public IConfiguration Configuration { get; }
public Startup(IConfiguration configuration)
{
Configuration = configuration
}
public void ConfigureServices(IServiceCollection services)
{
// add dependencies here
services.AddTransient<IVehiculoService, VehiculoService>();
}
}
