title: ImageCropper.Forms fails at initialization
body: <p>I'm trying to use ImageCropper.Forms, I have followed all steps but it fails in initialization and throws  this exception:</p>
  <p><code>Method not found: System.Threading.Tasks.Task`1&lt;Plugin.Media.Abstractions.MediaFile&gt; Plugin.Media.Abstractions.IMedia.TakePhotoAsync(Plugin.Media.Abstractions.StoreCameraMediaOptions)</code></p>
