.NET Framework - "AddressAlreadyInUse" error calling start() on TcpListener...

Hi:

I'm creating a simple port listener.  When I call start() method it returns

Int32 port = 80;
IPAddress localAddr = IPAddress.Parse( "127.0.0.1" );
TcpListener server = new TcpListener(port);
server = new TcpListener( localAddr, port );
server.Start();  // Get error here

Thanks,
Charlie

Hi,


Probably you already have another process running in port 80, did you try
another port?

Check if you have IIS running in your computer

Thanks Ignacio.  Needed to shut off IIS.

I am getting WCF software installed on the machine? Clean it out first. Are you installing as admin? Check your machine config or any *.config files to see if it is marked as read people coming across this same problem and many got their problem solved by uninstalling / reinstalling IIS. It did not solve my problem.
