MistakePage : https://www.fusetools.com/docs/fuse/controls/textview
This is wrong code block.
<TextView ux:Class="TextViewer" TextWrapping="Wrap" Padding="4" Margin="4" Color="#000" CaretColor="#000">
........
</TextView>
Sublime console tell me : ‘TextView’ does not have a property called ‘Color’ ;
There are also have some minor mistake in the Docs .I will push issues when I find new.
