Question

I’m now developing an app with reflect effect. I tried to assign a VisualBrush to Rectangle.Fill as:

<Rectangle.Fill>
   <VisualBrush Opacity="0.75" Stretch="None" Visual="{Binding ElementName=ReflectedVisual}">
   </VisualBrush> 
</Rectangle.Fill>

And VS reports VisualBrush doesn’t exist in my xml namespace. I manually added it to the XAML file using:

xmlns:fx=”http://schemas.microsoft.com/netfx/2007/xaml/presentation”

And added the reference DLL as well. However, now VS says that I cannot assign a VisualBrush to a property of class Brush.

This seemed weird to me, as I recalled the same code worked well on Vista. Does anyone know if there’s anything I’m missing here?

Thanks.

Metro apps do not have the same set of XAML brushes, resources and elements available as in WPF.

A work-around would have been to use a WriteableBitmap and use the Render method to draw the element to the bitmap. Unfortunately the current version does not support the Render method.
