Test project which recreates the transparent issue and static binding issue


So, looking forward to the next release of Forms ( for a fix to issues with tapping off a context action in iOS I installed

I have progress screens that are hidden until some action shows them, now they are ALL transparent no background colours get rendered for any control.

iOS - all transparent
 Android - All OK

I have a custom Renderer that no longer works and is not even called into. This now throws a null reference exception

This is caused by the following in the Xaml. This works prior to

Values="{x:Static moonviews:GradeView.All}"

Rolling back to Version works as it always has on both iOS and Android.

Test project attached.

I have checked this issue with Xamarin.Forms and I am not getting any Null reference exception.

Hence closing this issue.
