title: Windows store app sokets
body: <p>i am writing windows store app, that use sockets to send data via tcp protocol.
  i put this article as a starting point: <a href="http://msdn.microsoft.com/en-us/library/windows/apps/jj150599.aspx" rel="nofollow">http://msdn.microsoft.com/en-us/library/windows/apps/jj150599.aspx</a>
  but i cant understand some moments:
   1. when server send data to me (client) it is automaticaly "pushed" to DataReader reader ?
   2. are there any event that is called when data recieved, or i can ony manually look for UnconsumedBufferLength property in reader?
   3. does the data sends to server when i call witer.WriteByte(byte)?</p>
