Hi,

Just downloaded .NET 2.0 framework. However when I then launch MS Visual
Studio 2003, it seems like certain libraries from 2.0 are not recognized.
More specific, I'm trying the following code. Anyone knows I have to do
something else first?

using System;
using System.Net;
using System.Net.NetworkInformation;
using System.Text;

namespace Examples.System.Net.NetworkInformation.PingTest
{
   public class PingExample
   {
       // args[0] can be an IPaddress or host name.
       public static void Main (string[] args)
       {
           Ping pingSender = new Ping ();
           PingOptions options = new PingOptions ();

           // Use the default Ttl value which is 128,
           // but change the fragmentation behavior.
           options.DontFragment = true;

           // Create a buffer of 32 bytes of data to be transmitted.
           string data = "aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa";
           byte[] buffer = Encoding.ASCII.GetBytes (data);
           int timeout = 120;
           PingReply reply = pingSender.Send (args[0], timeout, buffer,
options);
           if (reply.Status == IPStatus.Success)
           {
               Console.WriteLine ("Address: {0}", reply.Address.ToString
());
               Console.WriteLine ("RoundTrip time: {0}",
reply.RoundtripTime);
               Console.WriteLine ("Time to live: {0}", reply.Options.Ttl);
               Console.WriteLine ("Don't fragment: {0}",
reply.Options.DontFragment);
               Console.WriteLine ("Buffer size: {0}", reply.Buffer.Length);
           }
       }
   }
}
