Uno: TextBlock.Background does not work in code behind

[Duefectu]

I have a project based on the UNO template for VS2017.
I need to create standard controls in code behind, like TextBlock, Grids, TextBox, etc...
I use the MainPage.xaml.cs in the uno.shared project.

The following code fails with the error CS1061: (Translated from Spanish) "_TextBlock does not contain a definition for "Background "or any "Background extension method is accessible to accept a first argument of type "TextBlock"(some missing using directive or an assembly reference?)_"

var control = new TextBlock();
control.Foreground = new SolidColorBrush(Color.FromArgb(255, 255, 0, 0));
control.Background = new SolidColorBrush(Color.FromArgb(255, 0, 255, 0));
control.Text = "Hello";
viewPort.Children.Add(control);

If I change TextBlock for another type of control like "TextBox", it works:
var control = new TextBox();
control.Foreground = new SolidColorBrush(Color.FromArgb(255, 255, 0, 0));
control.Background = new SolidColorBrush(Color.FromArgb(255, 0, 255, 0));
control.Text = "Hello";
viewPort.Children.Add(control);

Thanks for the good work with the uno platform!

The Background property doesn't exists in UWP's TextBlock.
To achieve the same behavior, you need to surround it with a Border

You are right, in UWP not exits, it's my mistake due to the existence in Android!
