如何获取 mac 地址

Question

我正在开发一个在 hololens2 上运行的 uwp 应用程序，我想获取 wifi mac 地址。

根据文档：Windows.Networking，我写了这段代码。

 // 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.PushNotifications.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");
         }
     }

但报错：WinRT originate error - 0x8007007F : 'The specified procedure could not be found.'。

似乎缺少dll，我找不到哪一个或两个？
