ContentPage.Resources not found.

HI guys,

Given the following xaml:
<?xml version="1.0" encoding="UTF-8"?>

<ContentPage.Content>
<ContentPage.Resources>

  <LayoutOptions x:Key="vertOptions"
                 Alignment="Center"
                 Expands="True" />

  <x:Double x:Key="borderWidth">
    3
  </x:Double>
</ResourceDictionary>

</ContentPage.Resources>

.....

I am getting a runtime error stating "Position 7:4. Type ContentPage.Resources not found in xmlns http://xamarin.com/schemas/2014/forms"

Just wondering whether anyone else has seen this?

When I remove the ContentPage.Resources xaml, the page works as expected. I took that xaml from the xamarin site.
