How to use ReceiveAsync in xamarin?

Question

Java

Here is an example using udpclient from .net

private static void UDPListener()
{
    Task.Run(async () =>
    {
        using (var udpClient = new UdpClient(11000))
        {
            string loggingEvent = "";
            while (true)
            {
                //IPEndPoint object will allow us to read datagrams sent from any source.
                var receivedResults = await udpClient.ReceiveAsync();
                loggingEvent += Encoding.ASCII.GetString(receivedResults.Buffer);
            }
        }
    });
}

I would like to understand how to use an analogue from Java.Net.DatagramSocket.ReceiveAsync

If not an example, then at least logic.
