CustomRenderer for Windows Phone always has a Control property of null?

I am building a custom renderer for my Windows Phone project. I tried many things, but no matter what I do, the Control property is null when entering the OnElementChanged callback.

Here's an example I just made where I am trying to make my own ImageRenderer.

using Xamarin.Forms;
using Xamarin.Forms.Platform.WinPhone;

[assembly: ExportRenderer(typeof(Image), typeof(Zooganizer.Apps.WinPhone.Renderers.ImageRenderer))]
namespace TestProject.Apps.WinPhone.Renderers
{
    public class ImageRenderer : Xamarin.Forms.Platform.WinPhone.ImageRenderer
    {
        protected override void OnElementChanged(ElementChangedEventArgs<Image> e)
        {
            //Control is null here always, which makes it hard for me to access the native control.
            base.OnElementChanged(e); 
        }
    }
}

I tried many things but without luck (for instance, trying to change the base from an ImageRenderer into something else). What am I doing wrong?

I am running and compiling the project through Visual Studio 2015 CTP 6.
