Xamarin.Forms IMediaPicker WinPhone

Hi All,

I working on an app that will run on Android and Windows Phone 8.0. This app must to be able to take photos. I found an easy way to do that by using IMediaPicker. However, it only works on Android. On WinPhone the code below returns null.

mediaPicker = DependencyService.Get<IMediaPicker>();

How can I get IMediaPicker on WinPhone? Any example?

Thanks in advance!
