title: how to add a windows phone project to existing Xamarin.Forms project
body: <p>I created a Xamarin.Forms Shared project in Xamarin Studio, so it did not add iOS or windows Phone project so I added it from Visual Studio then I added Xamarin.Forms package from nuget to both project now when I try to add the shared library to both ios and winphone by right clicking on references and add references, under solution I don't see the shared library only droid library is visible</p>
  
  <p>i went through the  <a href="http://developer.xamarin.com/guides/cross-platform/xamarin-forms/windows/getting-started/tablet/" rel="nofollow">Xamarin Docs</a>  i am following exactly what is written, what am i missing, or it is possible only in portable projects???</p>
