You must learn WRL and C++ based Store App:-) I think that you can create DeviceWatcher object #include "mozwrlbase.h" ComPtr<IDeviceInformationStatics> deviceInformationStatics; GetActivationFactory( HStringReference(RuntimeClass_Windows_Devices_Enumeration_DeviceInformation).Get(), deviceInformationStatics.GetAddressOf()); ComPtr<IDeviceWatcher> watcher; dviceInformationStatics->CreateWatcherAqsFilterAndAdditionalProperties(..., watcher.GetAddressOf()); Then, you can get IDeviceInformation via Add event.

Does this use for FxTV's service type only? If I have a test environment without TV, I can implement it.

To be more specific, we are trying to provide a unified XPCOM interface [1] for MDNS service discovery and service registration on all supported OS. For windows we need a replacement of MDNSResponderOperator [2] that connect to Windows API/Service.
