问题 I'm starting up a little code project to learn from the process, but I am not sure what's the best way of communicating between the different parts. First, I have a pure html/js client where the users need to get live updates frequently. Secondly, I'm considering having a web api application running to provide data.

问题 I have a few different WCF Services running. I would like to send one-way messages to clients who will be running IE 11.
