Hello guys

I am creating a wpf application in which I connect to android application through TCP listener. I made a separate class for tcp listener because i wanted to call it from all wpf forms.So till now its working fine from my main form but when i call tcp listener from another form i got an error i.e "Port is in use and only one port is permitted to use". If you have any solution please let me know..My code is

IPAddress localAddr = IPAddress.Parse(localIP);

TcpListener server = new TcpListener(localAddr, Port);

it works from Main form but when I call it from another form the error occurs.
Any suggestion and solution is welcome.

You can not have multiple listeners for same port. Are u sure about your code.

I have one tcp listener in my class . I am not creating instance when i am calling from different forms but i am getting this error too "A blocking operation was interrupted by a call to WSACancelBlockingCall"..I am using thread to start tcp listener .

Form or not form, does not matter. You use some symbols which are not declared in some scope, so what do you want?
And what are the "Form", in WPF?
