# Steps to reproduce
Clone the master samples project https://github.com/xamarin/xamarin-forms-samples (which uses Xamarin.Forms to 22.214.171.124)
Open the and execute the UWP EffectDemo https://github.com/xamarin/xamarin-forms-samples/tree/master/Effects/FocusEffect
And it works as expected with the background changing when the Entry element is focused or unfocused.
With Visual Studio 2017 choose "Manage Nuget for Solution" with pre release selected. Upgrade Xamarin.Forms from 126.96.36.199 to 188.8.131.52-pre3
Re-compile and deploy the the UWP project.
And the demo no longer works as expected, the BackgroundFocusBrush color is ignored.
# Expected behavior
The background color of Entry element should change when focused or unfocused.
# Actual behavior
The background color of Entry element does not change when focused or unfocused when using the pre release of xamarin forms.
