IActionFilter in 4.10

The IActionFilter in my plugin is not reached. What has changed with the new version?

In NopStartup I've this code:

        public void ConfigureServices(IServiceCollection services, IConfiguration configuration)
        {
            services.Configure<MvcOptions>(congig =>
            {
                congig.Filters.Add<MyFilter>();
            });
        }

My Filter,cs:

    class MyFilter : IActionFilter
    {
        public void OnActionExecuting(ActionExecutingContext filterContext)
        {
          ..........
        }
    }

Why it don't fire?

Thanks!
