WinRT: Get App Specific Hardware ID

[Igor2017]

Hello!
How to get App Specific Hardware ID on WinRT?
I need to call Windows::System::Profile::HardwareIdentification::GetPackageSpecificToken.

I try like this:

ComPtr<IHardwareIdentificationStatics> hardwareIdentificationStatics;
HRESULT hr = RoGetActivationFactory(HString::MakeReference(InterfaceName_Windows_System_Profile_IHardwareIdentificationStatics).Get(),
IID_PPV_ARGS(&hardwareIdentificationStatics));

But it is doesn't works...
Thanks.

Solution:

const WCHAR InterfaceName_Windows_System_Profile_HardwareIdentification[] = L"Windows.System.Profile.HardwareIdentification";
HRESULT hr;
ComPtr<IHardwareIdentificationStatics> hardwareIdentificationStatics;
hr = RoGetActivationFactory(HString::MakeReference(InterfaceName_Windows_System_Profile_HardwareIdentification).Get(),
                           IID_PPV_ARGS(&hardwareIdentificationStatics));
if (S_OK == hr) {
    ComPtr<IHardwareToken> hardwareToken;
    hr = hardwareIdentificationStatics->GetPackageSpecificToken(NULL, &hardwareToken);
    if (S_OK == hr) {
        ComPtr<IBuffer> buffer;
        hr = hardwareToken->get_Id(&buffer);
        if (S_OK == hr) {
            quint32 len;
            buffer->get_Length(&len);
            qDebug() << "get_Length" << len;
        }
    }
}
if (S_OK != hr)
    qWarning() << hr;
