Pointers to some education and code for server to web communication

I'm using .net in azure, and I'd like to ask/offer for assistance in orienting myself to a task. The task is quite simple: I want to create a service on a windows 2012 server which my website can use to communicate with my server. Any simple demonstration of opening communication with a service running on the server will do (but ideally  the approach will use current environment and be one that I can later develop for richer communication including wpf, chat and video stream).

So, the highest dream of what would help me, is if an expert who does this programming in C# can point to a tutorial that demonstrates building this, or who can pop off some extremely crude code, that just opens communication between the website and the server, just a "hello server" demo, that can also say "sorry, server is not answering". And a separate program that runs on the server. I know nothing about this server side communication service, and am interested in knowing how I can set up a wpf service that responds to queries from the website.

There are numerous options to communicate two process. They are named pipes, remoting, wcf, webservice, msmq.
As you have requested below links could be useful for you.
