Net.Sockets.TcpListener - need help

Hi,

I'm new to VB, and need help.

Here is the code I am trying to get to work:

VB Code:

Module Module1
 
    Sub Main()
        Dim server1 As New Net.Sockets.TcpListener(90)
        server1.Start()
        Console.WriteLine("server is waiting...")
    End Sub
 
End Module

The 'server1' on the first line gets the squiggly blue error-line under it.

I can't see what is wrong with it.

Plz help.

Do it like this. That is outdated.

VB Code:

Imports System.Net.Sockets
Imports System.Net
Module Module1
 
    Sub Main()
        Dim Myip As IPAddress = IPAddress.Parse("127.0.0.1")
        Dim server1 As New TcpListener(Myip, 90)
        server1.Start()
        Console.WriteLine("server is waiting...")
        Console.Read()
    End Sub
 
End Module

Edit: Changed the new tcplistener line. Doesnt need to be so long with the imports statement.

Thank you.
