I can't reproduce this behavior.

Is there something specific in your use case that could help to figure out the issue?

Hi dominique,
if u use lagend code below : i suppose that each service has only 1 layer and the legenda has a slider for change the opacity of this layer.
In this case the feature layer is displayer correctly on map but busy indicator never stop
Canu take a look at my code ?

thanks very much

In your MapLayerTemplate the busy indicator is always visible.
You have to add a binding to the BusyIndicatorVisibility:

 
<Grid x:Name="BusyIndicator" Background="Transparent" Margin="3,0" Visibility="{Binding BusyIndicatorVisibility}" ....
