We use the "ColorEdit" control to bind the "Foreground" attribute of "HighlightingStyle" in the form of MVVM. When the transparency of the color is zero, the code reports an error.

Hello,

Can you please let us know how to duplicate this in one of our samples?  We tried changing values in the Highlighting Style Viewer to make transparent colors and don't see any problems there in our testing.

Also, we already have checks in the code to ensure the text being rendered in TextStylePreview.OnDraw is not null before ever calling CanvasControl.CreateTextLayout.
