I am trying to make two labels each taking 50% of the width of the parent (the StackLayout) I tried with Fill, FillAndExpand, StartAndExpand on both Label's but it didn't work:
<StackLayout Orientation="Horizontal">
<Label Text="AAAAAAAAAAAAAAAAAAAAAAAAA" HorizontalOptions="FillAndExpand" />
<Label Text="BBBB" HorizontalOptions="FillAndExpand" />
</StackLayout>
