How do I get a Unique Identifier for a Device within Windows 10 Universal?

If you google a bit about this problem, you can’t find a right solution because all people are speaking about Hardware Token. Unfortunately this functionality doesn’t exists for Universal Windows Application.

There are at the moment only a way. You have to add the Extension reference “Windows Desktop Extensions for the UWP” or “Windows Mobile Extensions for the UWP“, then you can use the following code:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using Windows.Security.ExchangeActiveSyncProvisioning;
using Windows.System.Profile;

namespace PSC.Code
{
    public sealed class DeviceInfo
    {
        private static DeviceInfo _Instance;
        public static DeviceInfo Instance
        {
            get
            {
                if (_Instance == null)
                    _Instance = new DeviceInfo();
                return _Instance;
            }

        }

        public string Id { get; private set; }
        public string Model { get; private set; }
        public string Manufracturer { get; private set; }
        public string Name { get; private set; }
        public static string OSName { get; set; }

        private DeviceInfo()
        {
            Id = GetId();
            var deviceInformation = new EasClientDeviceInformation();
            Model = deviceInformation.SystemProductName;
            Manufracturer = deviceInformation.SystemManufacturer;
            Name = deviceInformation.FriendlyName;
            OSName = deviceInformation.OperatingSystem;
        }

        private static string GetId()
        {
            if (Windows.Foundation.Metadata.ApiInformation.IsTypePresent("Windows.System.Profile.HardwareIdentification"))
            {
                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).Replace("-", "");
            }

            throw new Exception("NO API FOR DEVICE ID PRESENT!");
        }
    }
}

Someone speaks about to use EasClientDeviceInformation provides a unique Id but this is working only for Windows Store Apps.

var deviceInformation = new EasClientDeviceInformation();
string Id = deviceInformation.Id.ToString();

Happy coding!
