title: System.Net.Http.HttpClient does not contain a definitions for TransportSettings
body: <p>I've got a problem. For beginning, this is my code:</p>
  
  <pre><code>HttpClient fond = new HttpClient();
  using (var client = new HttpClient())
  {
      HttpClient.TransportSettings.Credentials = new System.Net.NetworkCredential("username", "pwd");
  }
  var reponse = await fond.GetStreamAsync("" + TitleNewsGrid.Text);
  </code></pre>
  
  <p>For me everything is OK but (sorry It's my first app ^^') when I'm compile I found this error:</p>
