Hello puneethkv,

try this code: this is device id.

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);
    }

This is application id:

string appId = CurrentApp.AppId.ToString();

Hi khant,

Thanks for your reply..

The code you posted  is unique to specific apps, not for device.

Is there a way to get unique Id specific to device.

Thanks

Hello puneethkv,

Using EasClientDeviceinformation class you can get device id. Show link for briefly introduce of that class:

Answer 4

EasClientDeviceInformation Id is not unique.
You can try to use Device Mac Address as your Unique ID.

You can refer this to get the Mac Address

Answer 6

The correct answer is EasClientDeviceinformation.  There is no other device-specific ID for Windows RT, by design.

NOTE: If I ask for code, please provide something that I can drop directly into a project and run (including XAML), or an actual application project. I'm trying to help a lot of people, so I don't have time to figure out weird snippets with undefined objects and unknown namespaces.
