title: Is there any possibility to use TLS12 SslStream in Xamarin for Android?
body: <p>I know that Mono doesn't support TLS1.1 and TLS1.2 in current version of Xamarin so maybe there is possibility to implement TLS12 on my way?</p>
  
  <p>This part of code doesn't work for Xamarin.Android:</p>
  
  <pre><code>_clientSocket = new TcpClient();
  await _clientSocket.ConnectAsync(host, port);
  _stream = new SslStream(_clientSocket.GetStream(), false);
  _stream.AuthenticateAsClient(host, null, SslProtocols.Tls12, false);
  </code></pre>
