title: Group Chat Feature
body: <p>I want to add a chat to my xamarin.forms app.
  I've read alot of documentations about creating chats in c# but still I couldn't get an answer some of my questions:</p>
  
  <ul>
  <li>What is the best(performance) way to create a chatroom(like a groupchat) i've read using a thread per room could be a solution but this seems senseless to me ...</li>
  <li>Is there any Git-Projekt which implements a groupchat function where I can get some insights ?</li>
  <li>What do I have to keep in mind in terms of my infrastructure - how can I connect my chat to SQL ?</li>
  </ul>
  
  <p>I know these are alot of questions but I really dont  know where to start.
  I hope someone can help me out.</p>
