What is the difference between GHI.Premium.Net.EthernetENC28J60 and GHI.Networking.EthernetENC28J60

Before upgraded to R4 2014 this code worked fine, but after upgrade .Interface not exists

Gadgeteer.Modules.GHIElectronics.EthernetENC28 ethernet_ENC28 = new Gadgeteer.Modules.GHIElectronics.EthernetENC28.EthernetENC28(6);
GHI.Premium.Net.EthernetENC28J60 ethernet_ENC28J60 = ethernet_ENC28.Interface;

.Interface is deprecated?

I try with .NetworkInterface but not compile

There are no premium and open any longer. All libraries are merged and updated for a better user experience. Unfortunately, old code need to be updated.

so I have to delete all references to Premium and fix all code ?

Correct.
