Question

I create UserControl with size 1280x720, it does not fit into the screen if scale >= 175%. UserControl size can not be reduced. What can be done?

Answer 1

I find solution. I found the solution, it is necessary to use MainWindow.xaml ScaleTransform:

<Grid.LayoutTransform>
   <ScaleTransform x:Name="GlobalScale" ScaleX="1" ScaleY="1">
   </ScaleTransform>
</Grid.LayoutTransform>
