Static IP is missing from a virtual switch created with System Center 2012 Virtual Machine Manager SP1

Symptoms
When creating a virtual switch using System Center 2012 Virtual Machine Manager Service Pack 1 (SP1) on a Windows Server 2012 Hyper-V host with a static IP, the static IP information is not present on the virtual switch.
Cause
This can occur if a virtual network adapter is not created on the switch, or if the virtual network adapter doesn't have the setting "This virtual network adapter inherits settings from the physical management adapter" enabled.
Resolution

When creating a virtual switch on a Hyper-V host, if you want the NIC to send management information to Virtual Machine Manager then you need to create a Management virtual Network (VNIC) adapter. This VNIC needs to be connected to a virtual machine network that does not have isolation enabled. If a VNIC is not created, communication will only be allowed through the virtual machines that are connected.

If you want the static IP transferred to the virtual switch in Hyper-V, you need to check "This virtual network adapter inherits settings from the physical management adapter" when creating the VNIC, otherwise it will obtain a DHCP address.
