title: .Net Native - Type not included in compilation
body: <p>I found weird warning messages during .net native compilation for Universal App Platform - Windows 10.</p>
  
  <blockquote>
    <p>C:\Program Files (x86)\MSBuild\Microsoft.NetNative\x86\ilc\IlcInternals.targets(886,5): warning : Type 'Windows.UI.Xaml.Controls.Image' was not included in compilation, but was referenced in type 'XT.Controls.VideoPlayer.VideoPlayerControl'. There may have been a missing assembly.</p>

  <p>Application is not working correctly in release mode. I get crash after splashscreen with MissingMetadataException that requires to debug RuntimeType.cs (missing). </p>
  
  <p>Any ideas how can I include these types in compilation?</p>
