Usage example

In order to register your services you'll need to add following code to your Startup class:

    services.AddTransient<ServiceA>();
    services.AddTransient<ServiceB>();
    services.AddTransient<ServiceC>();
    services.AddByName<IService>()
        .Add<ServiceA>("key1")
        .Add<ServiceB>("key2")
        .Add<ServiceC>("key3")
        .Build();

Then you can use it via IServiceByNameFactory interface:

    public AccountController(IServiceByNameFactory<IService> factory) {
        _service = factory.GetByName("key2");
    }
