SocketException in Azure

[LarsBlaabjerg]

Hi,

I get a SocketException when using the UdpTraceListener in Azure (I changed the real IP/port in the trace below).

System.Net.Sockets.SocketException (0x80004005): An address incompatible with the requested protocol was used [::ffff:10.0.0.181]:9000
   at System.Net.Sockets.Socket.DoConnect(EndPoint endPointSnapshot, SocketAddress socketAddress)

The TcpTraceListener makes the process hang.

I found, that when creating the instance of System.Net.Sockets.Socket, if you specify the address family like this in Util.cs:

public static Socket OpenUdpSocket(IPAddress host, int port)
{
    var socket = new Socket(host.AddressFamily, SocketType.Dgram, ProtocolType.Udp);
    socket.Connect(host, port);
    return socket;
}

and like this in TcpSocketWriter.cs:

..
    try
    {
        var socket = new Socket(host.AddressFamily, SocketType.Stream, ProtocolType.Tcp);
        socket.Connect(host, port);
        return socket;
    }
    catch (SocketException e)
...

Things work the way they should.

Hope you fix it soon as I'd rather use the "official" version than compile my own.

I'm using the following setup:
Library Version: Splunk.Logging.TraceListener 1.1.0 and Splunk.Logging.Common 1.1.0
Platform: Azure, not really sure about anything more specific than that.
Framework Version: .NET 4.5.1, Visual Studio Professional 2013
Splunk Version: 6.2.1

Any chance this will ever make it into a release?
