In browsers that I tried, Edge and Chrome, the default app is located in top-left corner, even though the default XAML code states that the canvas has to be aligned horizontally to center.
Code: Select all
<Canvas Height="415" Width="320" Background="#FF161616" HorizontalAlignment="Center">
So, I feel this is a bug: the "HorizontalAlignment" property is not being evaluated correctly.
Strangely, if I add this VerticalAlignment="Top" to canvas element, the canvas is now located perfectly at top center of the page, as expected.
Something about vertical alignment is forcing correct evaluation of horizontal.
Please check and comment.
