If you want to register an instance, use the RegisterInstance method like this:

container
    .RegisterInstance<ICollection<IModifObserver>>(
        new Collection<IModifObserver>() { new NotifyHisto() });

If you want the container to return a new instance every time you resolve, then you can use the InjectionFactory class with the RegisterType method like this:

container
    .RegisterType<ICollection<IModifObserver>>(
        new InjectionFactory(
            c => new Collection<IModifObserver>() { new NotifyHisto() }));
