title: Project not Built in Active Configuration - Xamarin/Xamarin.Form
body: <p>I have downloaded Xamarin.Form sample projects from github <a href="https://github.com/xamarin/xamarin-forms-samples" rel="noreferrer">https://github.com/xamarin/xamarin-forms-samples</a></p>
  
  <p>Once I open any sample projects, it does not allow me to run on iOS Simulator.</p>
  
  <p>Does any one know how to handle this problem. I am using Xamarin Studio on Mac Operating System. </p>

  <p><strong>UPDATE-1:</strong></p>
  
  <p>I have also found the following useful article regarding my issue <a href="http://crossplatform.io/2013/12/02/setting-the-active-configuration-in-xamarin-studio/" rel="noreferrer">http://crossplatform.io/2013/12/02/setting-the-active-configuration-in-xamarin-studio/</a></p>
  
  <p>I chose <code>TabbedPageDemo.iOS--&gt; iOS|Debug</code> then I could able to see iOS part, however it still does not give me an option of <strong>Set As Start Project</strong></p>
