  • If you're building it from scratch for fun, then please pay no attention to me when I say that Websockets are a built-in feature of ASP.net 4.5. See here http://www.paulbatum.com/2011/09/getting-started-with-websockets-in.html – jessegavin Mar 15 '12 at 16:18
  • Is this different from [your question yesterday](http://stackoverflow.com/questions/9704633/receive-data-from-websocket-server-written-in-c-vb-net-as-image)? – simonc Mar 15 '12 at 16:20
  • The question was to use websocket for file transfer, apparently it's really complicated, so I try to ask for a basic one – Eldon Lesley Mar 16 '12 at 07:36
  • Here is to make it clear, I would like to create a server with a basic functionality to send message/string to the client (in browser) – Eldon Lesley Mar 16 '12 at 07:57

I would recommend you Fleck - very easy to start with and clean.

  • There is a console app project which shows you the implementation of a chat echo server. Very simple to use. You need to implement delegates for OnOpen, OnClose, OnMessage and can use Send to send data. – weismat Mar 16 '12 at 10:09
  • thanks! it worked! but I need to study the server first, since I need to modify it to send message to the client in string format (customizable) – Eldon Lesley Mar 16 '12 at 10:47
  • unfortunately though, I can't make a server from scratch, and this Fleck is a hell lot of complex code, and need some time to understand, but the usage is very simple – Eldon Lesley Mar 16 '12 at 11:30
  • There is a byte array and a string method - so you should be flexibale in your format - adding another send method should be really trivial. – weismat Mar 16 '12 at 11:43

You may also take a look at the WebSocketRPC library, which is simple enough. Some code snippets are shown on the page.
