error CS1022: Type or namespace definition, or end-of-file expected

I'm creating a messaging application for andriod/ios, but I am completely new to c# and networking, I've followed the first steps of a simple socket tutorial to get me started in networking (https://www.youtube.com/watch?v=KxdOOk6d_I0) but I get the error:

error "CS1022: Type or namespace definition, or end-of-file expected".

I'm assuming that it has something to do with the namespace because im new to c# and don't actually understand what the namespace does, but my compiler says there are no errors (I'm using visual studio code if that makes a difference) but it may be something else.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Net.Sockets;

namespace server_test
{
    class program
    {
        static void main(string[] args)
        {

            IPAdress ip = Dns.GetHostEntry("localhost").AdressList[0];
            TcpListener server = new TcpListener(ip, 8080);
            TcpClient client = default(TcpClient);

            try
            {
                server.Start();
                Console.WriteLine("server started...");
                Console.ReadLine();
            }catch (Exception ex)
            {
                Console.WriteLine(ex.ToString());
                Console.ReadLine();
            }

        }
    }
}

it should say server started..." or throw up an exeption but this is what im getting every time:

both answers are correct.

System.Net using was missing. There was a typo in addresslist.

One more problem was - The main function should be spelled as "Main" with capital M.

Full program:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Net.Sockets;
using System.Net;

namespace server_test
{
    class program
    {
        static void Main(string[] args)
        {

            IPAddress ip = Dns.GetHostEntry("localhost").AddressList[0];
            TcpListener server = new TcpListener(ip, 8080);
            TcpClient client = default(TcpClient);

            try
            {
                server.Start();
                Console.WriteLine("server started...");
                Console.ReadLine();
            }
            catch (Exception ex)
            {
                Console.WriteLine(ex.ToString());
                Console.ReadLine();
            }

        }
    }
}

The error shows The file could not be compiled. So, most probably it's compiler error. I guess below if it's not a typo, the spelling of ipaddress missing a d and so thus AddressList. 

 IPAddress ip = Dns.GetHostEntry("localhost").AddressList[0];

You are missing namespace import.

Add

using System.Net;

and fix the typo AdressList to AddressList
