title: SignalR: Can i send a message to the caller in a group?
body: <p>You can send a message to the caller if you don't use groups.
  But I want to be able to send a message to a client when he joins the group.
  Is this possible?</p>
  
  <p>This is what I am using now:</p>
  
  <p><strong>To caller if not using groups</strong></p>
  
  <pre><code>await Clients.Caller.SendAsync("update", "You have connected to the server.");
  </code></pre>
  
  <p>And this is what I found.</p>
  
  <p><strong>From the working with groups page on the Microsoft website</strong>
  <br/>
  <br/>
  Send to <strong>all</strong> in group.</p>
  
  <pre><code>Clients.Group(groupName).addChatMessage(name, message);
  </code></pre>
  
  <p>All clients <strong>except specified</strong>.</p>
  
  <pre><code>Clients.Group(groupName, connectionId1, connectionId2).addChatMessage(name, message);
  </code></pre>
  
  <p>All clients <strong>except caller</strong></p>
  
  <pre><code>Clients.OthersInGroup(groupName).addChatMessage(name, message);
  </code></pre>
