Accessing System.Net.Sockets?

I have a problem with the server socket. It has to be something on a remote control. I'm trying to do it this way:

Code:

using System;
using System.Net;
using System.Net.Sockets;
using System.Text;
using System.Threading;using Oxide.Core;
using Oxide.Core.Libraries;namespace Oxide.Plugins
{
    class Remote : HurtworldPlugin
    {
        void Init()
        {
            IPEndPoint localEndPoint = new IPEndPoint(IPAddress.Parse("127.0.0.1"), 29000);
            //IPEndPoint localEndPoint = CreateIPEndPoint("127.0.0.1:29000");            // Create a TCP/IP socket.
            Socket listener = new Socket(AddressFamily.InterNetwork,
                SocketType.Stream, ProtocolType.Tcp);            // Bind the socket to the local endpoint and listen for incoming connections.
            listener.Bind(localEndPoint);
            listener.Listen(100);            // ...        }
    }
}

But I getting an error:

Code:

15:13 [Error] Failed to initialize plugin 'Remote v1.0.0' (UnauthorizedAccessException: System access is restricted, you are not allowed to use System.Net.IPEndPoint)
15:13 [Debug]   at Oxide.Plugins.Remote.DirectCallHook (System.String name, System.Object& ret, System.Object[] args) [0x00000] in <filename unknown>:0

How to properly do a simple socket?

 

From your other posts I know that the extension should be placed in Hurtworld_Data/Managed. But how to do them? It must be in the format .dll? You can give tips on how you can do extension?

 

Thanks, socket works. I have not used before C#. How in the extension call any server command and chat command? I have a problem to get to ConsoleManager.Instance?.ExecuteCommand() or similar method executeCommand in extension.
