title: App.AppName in xamarin forms
body: <p>I create a new XF project using 4.0.4.4 XF.  Nowhere can I find App.AppName.  I'm trying to follow the tutorial at 
  <a href="https://developer.xamarin.com/guides/xamarin-forms/web-services/authentication/oauth/" rel="nofollow noreferrer">https://developer.xamarin.com/guides/xamarin-forms/web-services/authentication/oauth/</a> where it is definitely referenced in docs. </p>
  
  <p>If I create a public property in PCL / App.cs with AppName it appears to work fine.  Is this the right way? </p>
  
  <p>Usage in the tutorial
  The following code example shows how an Account object is securely saved on the iOS platform:</p>
  
  <pre><code>AccountStore.Create ().Save (e.Account, App.AppName);
  </code></pre>
  
  <p>The following code example shows how an Account object is securely saved on the Android platform:</p>
  
  <pre><code>AccountStore.Create (Context).Save (e.Account, App.AppName);
  </code></pre>
