Where did nop.services.common.GenericAttributeExtensions move to in nop4.1

Hi

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?

The answer was right before me ha ha.

        

    
var shippingOptions = _genericAttributeService.GetAttribute<List<ShippingOption>>(OfferedShippingOptions, _storeContext.CurrentStore.Id);
