    .AddSingleton<IService, ThirdService>(sp => new ThirdService(  // register named dependency using factory
        sp.GetRequiredService<IService>(nameof(FirstService)),  // resolve named dependency
        sp.GetRequiredService<IService>(nameof(SecondService))  // resolve named dependency
    ), nameof(ThirdService));

    .AddSingleton<Service>()
    .AddFactory<Service>()  // registers Func<Service>
