I am currently migrating a plugin from nop 3.7 to 4.1
In nop 3.7 I could call:
var shippingOptions = _workContext.CurrentCustomer.GetAttribute<List<ShippingOption>>(SystemCustomerAttributeNames.OfferedShippingOptions, _storeContext.CurrentStore.Id);
It seems the implementation of generic attributes has moved away from the extensions.
Should I now be using the GenericAttributeService class to implement this?
