[Capability usage] The privateNetworkClientServer capability provides inbound and outbound access to home and work networks through the firewall. This capability is typically used for games that communicate across the local area network (LAN), and for apps that share data across a variety of local devices. If your app specifies musicLibrary, picturesLibrary, or videosLibrary, you don't need to use this capability to access the corresponding library in a Home Group. On Windows, this capability does not provide access to the Internet. On Windows Phone, this capability provides the same access as internetClient or internetClientServer. [Capability scenario]
