Network Resource Pool and being compatible with virtual switches in Hyper-v

Hi

in the book " Windows Server 2012 Hyper-V Cookbook" , Copyright © 2012 Packt Publishing, by Leandro Carvalho, chapter 3, pp. 65-69:

It is written that the only way to enable Network Resources Pool is Powershell and some commandlets.

e.g: New-VMResourcePool –Name StoragePool1 –ResourcePoolType VHD –Paths C:\Hyper-V\StoragePool1

it works but he didn't say anything about NRP (Network Resources Pool) it work!!!

and he said about "Ethernet resource pool":

it runs but when i want to put network adapter in the resource pool, the only virtual switch is Automatic connection and it doesn't show me my virtual switches. it erros when i apply with this configuration : Resource pool : ... and virtual awitch : automatic connection. (Error applying network adapter changes.) the connection cannot be enabled because resource pool does not have any assigned virtual switches.!! 

what can i do with VHD Network Resources Pool and how can i solve Ethernet Resource Pool?

thank btw.
