title: Xamarin Forms how to check it contains the latest Api for Android and iOS
body: <p>Hi newbie on Xamarin Forms. <br/>
   I am a bit of confuse on using Xamarin forms. 
  With the following questions, I hope you can help me to understand to use it for development. <br/></p>
  
  <p>Currently I am using VS2015 Community version<br/></p>
  
  <p>1) If I have done the Settings on Cross Platform development to include C#/.Net(Xamarin v4...), do I still need to download the Xamarin at Xamarin.com?<br/></p>
  
  <p>2) Understand Android and iOS have different Api level (Sdk ver) and iOS ver8,9,10 respectively.<br/>
  So, When google releases new api or Apple releases new iOS ver, How do I update Xamarin to  use them? what I need to and How I handle Android and iOS new update respectively? What are the steps to take?<br/></p>
  
  <p>3) If I have Updated Xamarin, is this means it has included all the latest Api for Android and iOS<br/></p>
  
  <p>4) Can I use Xamarin for VS2017 as compare to VS2015 is more matured?<br/></p>
  
  <p>Thanks</p>
