no exception raised on running both server in same port

[himadrinath]

@burakoner started server on 8080 one in on debug mode and other one in without debug mode.

but it didn't raised any exception that telling me that the port is busy or something.

is this right behavior

I got an exception as below

System.Net.Sockets.SocketException: 'Only one usage of each socket address (protocol/network address/port) is normally permitted.'

from your example code

i tried out one without debug and then next one with debug no exception

using System.Text;
