title: The best way to save Configuration data in Xamarin.Forms based app?
body: <p>I am now working on an Xamarin.Forms based app, and have few questions about this. Is there a best way for me to just save some configuration data? As I am using an MVVM based app in like this</p>
  
  <pre><code>private bool _isActive;
  public bool IsActive
  {
     get { return _isActive; }
     set
     {
        _isActive = value;
        RaisePropertyChanged(nameof(IsActive))
     }
  }
  </code></pre>
  
  <p>I wanted to save the "IsActive" value when use it other time I load my app.<br>
  So is there a best way for me to do this? </p>
