Hi,

I am working with metro apps. In that i need to send toast notifications to the app. In order to send only one toast notification for the device i need to have only one channel uri per device. But below mentioned function is returning different guid's if hardware changes.

private string GetHardwareId()
{
    var token = HardwareIdentification.GetPackageSpecificToken(null);
    var hardwareId = token.Id;
    var dataReader = Windows.Storage.Streams.DataReader.FromBuffer(hardwareId);

    byte[] bytes = new byte[hardwareId.Length];
    dataReader.ReadBytes(bytes);

    return BitConverter.ToString(bytes);
}

Actually I am using other apps also. for those apps am getting only one toast notification. I want the same thing to be implemented in my app.

please suggest me your ideas.



thanks.
