I used the term “External Communication” simply because I do not mind which method I need to use to be able to send a simple message like “hey, how’s it going?” to another person on a different computer who’s also running my application.
I’ve tried literally hundreds of samples, edited them, corrected various errors, came up with some of my own stuff, and nothing ever works.
I can send and receive messages to myself on the same computer but I can never be able to get a friend to connect to my server program. Using port 80, or 8080, or 1009 but i’ve also tried many other numbers too lol – no luck! I’ve read documentation many times, and several articles from all over the web and also used those examples, still no luck.
Does anybody have any idea on how i can send and receieve simple messages between computers?
Sounds like a classic case for a WCF app with peer-to-peer binding.
Check out some of those links for articles and blog post that show you have to do it:
