Hi,

Do you have stack trace that you can provide?

Thanks

Hi,
I'm having the same problem as stated above. I'm using the latest library version from NuGet (1.8.3) on a x64 windows 10. I'm always getting the error "An entry with the same key already exists.":

System.ArgumentException
  HResult=0x80070057

Here is sample exmple code (console application) to reproduce the issue.

using System;
using System.Collections.Generic;
using System.Threading.Tasks;
using System.IO.Ports;
using System.Threading;
using MessagingToolkit.Core;
using MessagingToolkit.Core.Mobile;

namespace GatewayDiscoveryCmd
{
    class Program
    {
        public struct GatewayInfo
        {
            public String Port { get; set; }

            public String DeviceModel { get; set; }

            public String DeviceManufacturer { get; set; }
        }

        static void Main(string[] args)
        {
            string[] ports = SerialPort.GetPortNames();
            List<Task<GatewayInfo>> discoveryTasks = new List<Task<GatewayInfo>>();

            Console.WriteLine(String.Format("Scanning {0} ports ...", ports.Length));

            foreach (string port in ports)
            {
                Task<GatewayInfo> task = Task<GatewayInfo>.Factory.StartNew(() => GetGatewayInfo(port));
                discoveryTasks.Add(task);
            }

            Task.WaitAll(discoveryTasks.ToArray());

            foreach (Task<GatewayInfo> task in discoveryTasks)
            {
                GatewayInfo gatewayInfo = task.Result;
                Console.WriteLine(String.Format("Gateway at port {0} is model {1} by {2}", gatewayInfo.Port, gatewayInfo.DeviceModel, gatewayInfo.DeviceManufacturer));
            }
        }

        private static GatewayInfo GetGatewayInfo(string portName)
        {
            // TODO Remove this statement if everything goes well, its only for debugging
            Console.WriteLine("Task created at {0} on thread #{1}.", DateTime.Now.Ticks, Thread.CurrentThread.ManagedThreadId);

            // Predefine the model and manufacturer
            string deviceModel = "";
            string deviceManufacturer = "";

            MessageGateway<IMobileGateway, MobileGatewayConfiguration> messageGateway = MessageGateway<IMobileGateway, MobileGatewayConfiguration>.NewInstance();

            MobileGatewayConfiguration mobileGatewayConfiguration = MobileGatewayConfiguration.NewInstance();
            mobileGatewayConfiguration.GatewayId = portName;
            mobileGatewayConfiguration.PortName = portName;
            mobileGatewayConfiguration.BaudRate = PortBaudRate.BitsPerSecond115200;
            mobileGatewayConfiguration.DataBits = PortDataBits.Eight;
            mobileGatewayConfiguration.StopBits = PortStopBits.One;
            mobileGatewayConfiguration.DtrEnable = true;
            mobileGatewayConfiguration.RtsEnable = true;
            mobileGatewayConfiguration.Parity = PortParity.None;
            mobileGatewayConfiguration.Handshake = PortHandshake.None;
            mobileGatewayConfiguration.DisablePinCheck = true;

            // Find the mobile gateway according to the configuration
            IMobileGateway mobileGateway = messageGateway.Find(mobileGatewayConfiguration);

            if (null == mobileGateway)
            {
                throw new Exception("The mobile gateway could not be initialized! Please check the log files!");
            }

            // Get the device information
            deviceModel = mobileGateway.DeviceInformation.Model;
            deviceManufacturer = mobileGateway.DeviceInformation.Manufacturer;

            // Disconnect the mobile gateway
            mobileGateway.Disconnect();
            mobileGateway.Dispose();
            mobileGateway = null;

            return new GatewayInfo { Port = portName, DeviceModel = deviceModel, DeviceManufacturer = deviceManufacturer };
        }
    }
}

Crazy, seems to work after disabling the watchdog...
