Using a hub on port 80 for signal r

Question

I at the moment I am polling a web service from my c# desktop winform app to retrieve messages as and when they come in. Instead of polling I thought maybe it would be better to receive a 'push' notification? this lead me to the SignalR framework. As I understand you have to create a hub on the server. But, can i use port 80 or will I get an error stating that the port is is use by iis? If so, is there an alternative to what I can do?

thanks

Two processes can not bind to the same port. If you have IIS running on port 80, you'll have to either proxy the other software through IIS or run it on a different port.
