Windows requirements

Requirements Description
Device family
Windows 10 (introduced in 10.0.10240.0 - for Xbox, see UWP features that aren't yet supported on Xbox)
API contract
Windows.Foundation.UniversalApiContract (introduced in v1.0)

Examples

Enumerate LAN identifiers (C#):

using Windows.Networking.Connectivity;

var identifiers = NetworkInformation.GetLanIdentifiers();
foreach (var id in identifiers)
{
 var infra = id.InfrastructureId;
 var port = id.PortId;
 var type = id.NetworkAdapterId;
 // App-specific: correlate infra/port values with diagnostics telemetry.
}

Remarks

Location data is expressed either as a BSSID if the network adapter media type is Wireless LAN, or as a tuple <ChassisId, Port Number> if the network adapter type is Ethernet. The data is represented according to the LLDP protocol.

Properties

Name Description
InfrastructureId

Gets a LanIdentifierData object containing locality identification information for the network adapter's connection.
NetworkAdapterId

Gets the adapter GUID that identifies the network adapter to associate with the locality information.
