Get UDID of iphone on Connect c#

The link to documentation of IMobileDevice-net seems broken. But you can find it at Documentation of IMobileDevice-net

Based on sample code provided for IMobileDevice-net one can find UDID of device if Name of the device is known. The code snippet for the same is:

ReadOnlyCollection<string> udids;
int count = 0;

var idevice = LibiMobileDevice.Instance.iDevice;
var lockdown = LibiMobileDevice.Instance.Lockdown;

// Get all devices connected
var ret = idevice.idevice_get_device_list(out udids, ref count);

if (ret == iDeviceError.NoDevice)
{
    // Not actually an error in our case
    return;
}

ret.ThrowOnError();

// Variable to store UDID of 
string foundUDID = "";
var nameOfDevice = "NameOfYourDevice";

// Get the device name
foreach (var udid in udids)
{
    iDeviceHandle deviceHandle;
    idevice.idevice_new(out deviceHandle, udid).ThrowOnError();

    LockdownClientHandle lockdownHandle;
    lockdown.lockdownd_client_new_with_handshake(deviceHandle, out lockdownHandle,
     "Quamotion").ThrowOnError();

    string deviceName;
    lockdown.lockdownd_get_device_name(lockdownHandle, out deviceName).ThrowOnError();


    deviceHandle.Dispose();
    lockdownHandle.Dispose();

    if(deviceName.equals(nameOfDevice))  //Check if name matches
    {
       foundUDID = udid;
       break;
    }

}

I'm now trying to implement the code above on Connect and I am using LibUsbDotnet DeviceNotify library for On connect events, but the issue now is the imobiledevice only returns info when I have two devices connected, it returns blank if only one device connected. On two device connected it shows the device #1 information.

here is my code

using iMobileDevice;
using iMobileDevice.iDevice;
using iMobileDevice.Lockdown;
using System;
using System.Collections.Generic;
using System.Collections.ObjectModel;
using System.Collections.Specialized;
using System.Linq;
using System.Runtime.InteropServices;
using System.Text;
using System.Threading.Tasks;
using LibUsbDotNet.DeviceNotify;
using System.Windows.Forms;

namespace MobileDeviceDemo
{
    class Program
    {
        public static IDeviceNotifier UsbDeviceNotifier = DeviceNotifier.OpenDeviceNotifier();
        static void Main(string[] args)
        {

            //// Hook the device notifier event
            UsbDeviceNotifier.OnDeviceNotify += OnDeviceNotifyEvent;

            ////NativeLibraries.Load();



            // Exit on and key pressed.
            Console.Clear();
            Console.WriteLine();
            Console.WriteLine("Waiting for USB Devices connection");
            Console.Write("[Press any key to exit]");

            while (!Console.KeyAvailable)
                Application.DoEvents();

            UsbDeviceNotifier.Enabled = false;  // Disable the device notifier

            // Unhook the device notifier event
            UsbDeviceNotifier.OnDeviceNotify -= OnDeviceNotifyEvent;
            //GenerateUDIDs();
            //Console.ReadLine();


        }

        private static void OnDeviceNotifyEvent(object sender, DeviceNotifyEventArgs e)
        {
            if (e.EventType.ToString() == "DeviceArrival")
            {
                Console.WriteLine("\n Device Connected");

                GenerateUDIDs();
            }

        }

        private static void GenerateUDIDs()
        {
            NativeLibraries.Load();

            ReadOnlyCollection<string> udids;
            int count = 0;

            var idevice = LibiMobileDevice.Instance.iDevice;
            var lockdown = LibiMobileDevice.Instance.Lockdown;

            var ret = idevice.idevice_get_device_list(out udids, ref count);

            if (ret == iDeviceError.NoDevice)
            {
                // Not actually an error in our case
                Console.WriteLine("No devices found");
                return;
            }

            ret.ThrowOnError();

            int NumberOfDeviceConnected = udids.Count;
            Console.WriteLine($"\n Number of Devices Connected: {NumberOfDeviceConnected}");

            int ctr = 0;
            // Get the device name
            foreach (var udid in udids)
            {
                ctr++;
                iDeviceHandle deviceHandle;
                idevice.idevice_new(out deviceHandle, udid).ThrowOnError();

                LockdownClientHandle lockdownHandle;
                lockdown.lockdownd_client_new_with_handshake(deviceHandle, out lockdownHandle, "Quamotion").ThrowOnError();

                string deviceName;
                lockdown.lockdownd_get_device_name(lockdownHandle, out deviceName).ThrowOnError();

                string sn;
                iMobileDevice.Plist.PlistHandle tested1;
                lockdown.lockdownd_get_value(lockdownHandle, null, "SerialNumber", out tested1).ThrowOnError();

                //Get string values from plist
                tested1.Api.Plist.plist_get_string_val(tested1, out sn);


                Console.WriteLine($"\n device: {ctr} Name: {deviceName}  UDID: {udid}  Serial Number: {sn}");

                deviceHandle.Dispose();
                lockdownHandle.Dispose();
            }
        }
    }
}

and the output is:

[Press any key to exit]

Apparently iMobileDevice Code is not triggering response on the first connect, Any Help on this would greatly be appreciated
