services.AddSingleton<RootEvent1Subscriber>();
services.SubscribeAsync<BaseEvent1, RootEvent1Subscriber>(lifetime: SubscriberLifetime.Singleton);

services.AddScoped<Event1Subscriber>();
services.SubscribeAsync<Event1, Event1Subscriber>();

// IEventAggregator eventAggregator
// both RootEvent1Subscriber and Event1Subscriber subscribe on Event1
await eventAggregator.PublishAsync(new Event1 { Payload = payload1 });
