i'm working on a uwp app runing on hololens2, i want get the wifi mac address.

according to this documents: Windows.Networking, i wrote this code.

 // part of includes at pch.h
 #include <winrt/Windows.ApplicationModel.Activation.h>
 #include <winrt/Windows.ApplicationModel.Core.h>
 #include <winrt/Windows.Foundation.h>
 #include <winrt/Windows.Foundation.Collections.h>
 #include <winrt/Windows.Foundation.Metadata.h>
 #include <winrt/Windows.Data.Xml.Dom.h>
 #include <winrt/Windows.Devices.h>
 #include <winrt/Windows.Devices.WiFi.h>
 #include <winrt/Windows.Devices.WiFiDirect.h>
 #include <winrt/Windows.Devices.Sms.h>
 #include <winrt/Windows.Networking.h>
 #include <winrt/Windows.Networking.BackgroundTransfer.h>
 #include <winrt/Windows.Networking.Connectivity.h>
 #include <winrt/Windows.Networking.NetworkOperators.h>
 #include <winrt/Windows.Networking.Proximity.h>

 #include <winrt/Windows.Networking.ServiceDiscovery.Dnssd.h>
 #include <winrt/Windows.Networking.Sockets.h>
 #include <winrt/Windows.Networking.Vpn.h>

 // some cpp function
    
     void MainPage::ClickLoginHandler(IInspectable const&, RoutedEventArgs const&)
     {
         using namespace winrt::Windows::Foundation::Collections;
         using namespace winrt::Windows::Networking;
         using namespace winrt::Windows::Networking::Connectivity;
         using namespace winrt::Windows::Networking::NetworkOperators;
         ConnectionProfile profile = NetworkInformation::GetInternetConnectionProfile();
         NetworkOperatorTetheringManager manager = 
NetworkOperatorTetheringManager::CreateFromConnectionProfile(profile); // error on the line
         IVectorView<NetworkOperatorTetheringClient> clients = manager.GetTetheringClients();
         for (NetworkOperatorTetheringClient client : clients)
         {
             OutputDebugString(client.MacAddress().c_str());
             OutputDebugString(L"\r\n");
         }
     }

but it reports an error: WinRT originate error - 0x8007007F : 'The specified procedure could not be found.'。

it seems missing dll, and i can not found out which one, or two?

if you know that please let me know.
