ASP.NET Core - Dependency Injection

My controller:

    [Route("api/[controller]")]
    [ApiController]
    public class CategoriesController : ControllerBase
    {
        private readonly IUnitOfWork unitOfWork;

        public CategoriesController(IUnitOfWork unitOfWork)
        {
            this.unitOfWork = unitOfWork;
        }

        [HttpGet]
        [Route("TestCategories")]
        public ActionResult<IEnumerable<Category>> TestCategories()
        {
            return unitOfWork.Categories.FindAll().ToList();
        }
    }

My Startup:

        public void ConfigureServices(IServiceCollection services)
        {
            services.Configure<CookiePolicyOptions>(options =>
            {
                // This lambda determines whether user consent for non-essential cookies is needed for a given request.
                options.CheckConsentNeeded = context => true;
                options.MinimumSameSitePolicy = SameSiteMode.None;
            });

            services.AddDbContext<ClassifiedAdsDbContext>(options => options.UseSqlServer(Configuration.GetConnectionString("DefaultConnection")));
            services.AddScoped<IUnitOfWork, UnitOfWork>();
            services.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_2_1);
        }

I did break my app so i can understand how the codes work.

As you can see on my controller i used IUnitOfWork (Interface that comes from MyProject.Domain - class library) 

Scenario:

  1. if i use the UnitOfWork class, the only thing the i need to inject (to startup.cs) is the UnitOfWork class only.
  2. if i use the IUnitOfWork interface. i need to inject both (to startup.cs) IUnitOfWork interface and UnitOfWork class as well because it gives error see below.
