ccrewrite error when trying to set TextBox.Margin in UWP project when targeting ARM platform

[dfch]

I get the following error when building an UWP application for ARM:

Could not resolve member reference: Windows.UI.Xaml.FrameworkElement::put_Margin.

This happens only when CodeContracts are enabled (v1.9.10714.2, see screenshot) and ONLY when Solutions Platform is set to ARM (I try to build for IoT; there is no error when trying to build for x64 or x86)

I use UWP target version 10.0.14393 (for min and max):

The code I use to reproduce the behaviour is a simple constructor that creates a TextBox and sets a Margin:

public sealed partial class ArbitraryPage : Page
{
  public ArbitraryPage()
  {
    this.InitializeComponent();

    var textBox = new TextBox()
    {
      Text = item,
      IsReadOnly = true,
      Margin = new Thickness(10),
    };
  }
}

Note: when omitting the Margin = ... line there is no error.
