title: Receive data from websocket server (written in c#/vb.net) as image
body: <p>I'm kind of new in the websocket,
  I learned the client-side code (in JavaScript) which is simple and easy,</p>
  
  <p>but when I search the websocket server, the code is complicated (especially in c#),
  and now I need a websocket server code (in c# or vb.net) that return some message to the client side (can be a string like "hello client") as an example and if possible with some explanation in the code,
  and furthermore I also need some code for the server to send file (like .jpg) to the client side (if it's possible)</p>
  
  <p>any idea? or if you have a good reference, I'm open to it,
  Thanks</p>
