使用System.Net.Sockets;不支持在Windows商店应用程序架构，用什么代替

我在windows窗体中创建了一个简单的客户端和服务器应用程序，现在我想在windows商店应用程序框架中创建它。使用System.Net.Sockets;那里不支持。我应该如何处理这个问题，我应该使用什么类?以下是winforms c#的代码:many thanks

using System.Net;
using System.Net.Sockets;
using System.Net.NetworkInformation;
using System.Media;
namespace ChatClient
{
    public partial class Form1 : Form
    {
        Socket sck;
        EndPoint epLocal, epRemote;
        public Form1()
        {
            InitializeComponent();
          //what would I use instead in windows store app, using System.Net.Sockets; namespace isnt supported ?
            sck = new Socket(AddressFamily.InterNetwork, SocketType.Dgram, ProtocolType.Udp);
            sck.SetSocketOption(SocketOptionLevel.Socket, SocketOptionName.ReuseAddress, true);
        }

        //Getting local IP address through code
        private string GetLocalIP()
        {
            IPHostEntry host;
            string localIP = "";
            host = Dns.GetHostEntry(Dns.GetHostName());
            foreach (IPAddress ip in host.AddressList)
            {
                if (ip.AddressFamily == AddressFamily.InterNetwork)
                {
                    localIP = ip.ToString();
                    break;
