IServiceProvider Constructor injection

ActionMethod.cs

public ActionResult Index(string[] array)
{
    int[] result = [0];
    
    using (var scope = _serviceProvider.CreateScope())
    {
        var service = scope.GetService<IArrayReversalService>();

        result = await service.Reverse(array);
    }
    
    return View(result);
}

Controller1.cs

public class HomeController : Controller
{
    private readonly ILogger<HomeController> _logger;
    private readonly IArrayReversalService _arrayReversalService;
    
    // more fields for injected services

    public HomeController(ILogger<HomeController> _logger, IArrayReversalService _arrayReversalService, ... more services)
    {
        _arrayReversalService = serviceProvider.GetService<IArrayReversalService>();
        _logger = serviceProvider.GetService<ILogger<HomeController>>();
        
        // More services assigned
    }
}

Controller2.json

private readonly IServiceProvider _serviceProvider;
    
public HomeController(IServiceProvider serviceProvider)
{
    _serviceProvider = serviceProvider;
}

Program.cs

// uses the same syntax to add the service in Program.cs
builder.Services.AddTransient<IArrayReversalService, ArrayReversalService>();
