    The game already runs on iOS and Android. I want to port it to the windows store and I'm having trouble figuring out how get the sockets to work. Is there a plugin i can use or what?. I'm using them to get NTP time in this code:

    public static DateTime GetNetworkTime()
    {
    try
    {
    const string ntpServer = "pool.ntp.org";
    var ntpData = new byte[48];
    ntpData[0] = 0x1B; //LeapIndicator = 0 (no warning), VersionNum = 3 (IPv4 only), Mode = 3 (Client Mode)

    var addresses = Dns.GetHostEntry(ntpServer).AddressList;
    var ipEndPoint = new IPEndPoint(addresses[0], 123);
    var socket = new Socket(AddressFamily.InterNetwork, SocketType.Dgram, ProtocolType.Udp);



    socket.Connect(ipEndPoint);
    socket.ReceiveTimeout = 2000;
    socket.Send(ntpData);
    socket.Receive(ntpData);



    socket.Close();

    ulong intPart = (ulong)ntpData[40] << 24 | (ulong)ntpData[41] << 16 | (ulong)ntpData[42] << 8 | (ulong)ntpData[43];
    ulong fractPart = (ulong)ntpData[44] << 24 | (ulong)ntpData[45] << 16 | (ulong)ntpData[46] << 8 | (ulong)ntpData[47];

    var milliseconds = (intPart * 1000) + ((fractPart * 1000) / 0x100000000L);
    var networkDateTime = (new DateTime(1900, 1, 1)).AddMilliseconds((long)milliseconds);
    return networkDateTime;

    }
    catch (SocketException) { Debug.Log("Did not get date from NTP server!!"); return new DateTime(); }

    }

    Ty you for the anwser. I'm going to go with using the WinRT API. Do I need to add a plugin to the unity project or just a reference to the proper assemblies in the code ?

    If you're building for WSA or WP8.1, you can write directly in Unity script code, but need to wrap that code with #if NETFX_CORE / #endif, the needed assemblies are already referenced.

    You can also go with this approach, as it will let you quickly test and build the code:
    * In Unity scripts, add static delegates for Network functions you need
    * Set delegates from for ex., App.xaml.cs
    * Build & Run
    * When you'll execute Network code from Unity script, it will call into your callback from App.xaml.cs
    * If you need to tweak something, it will be enough to recompile VS solution.

    Ok. I got confused since I'm using visual studio tools to write my code directly in Vs2013 and when it wasnt auto-completing the Windows.(whatever) references I got worried. If i wrap them in #if NETFX_CORE I wont get compile errors and it will still run on the windows platforms. I think I got it now
