UWP XAML x:Bind inherited interfaces are not recognized

Yes, after doing some test and reseach, it seems that inherited interface-properties are not recognized by the compiler when using the X:Bind.

As a workaround we can use the traditional Binding instead of the X:Bind as following:

In the .xaml:

<Grid Name="MyRootGrid">
         <TextBlock Text="{Binding A}"></TextBlock>
</Grid>

In the xaml.cs:

MyGrid.DataContext = TheObject;
