I'm learning the Silverlight API (2.2) by building a sample app and incorporating many of the features found in the interactive SDK.I've noticed a difference in the results returned from the ScaleLine and the MeasureAction measure tool. Please see the attached image, showing that the MeasureAction result in red displays 2 miles, where the ScaleLine displays 1 mile. I can confirm that the ScaleLine is correct, where the MeasureAction results are ~ 1.5-2x inflated. ScaleLine definition: <esri:ScaleLine Margin="5"
MapUnit="Meters"
VerticalAlignment="Bottom"
HorizontalAlignment="Left"
Map="{Binding ElementName=Map}" />MeasureAction definition: <esri:MeasureAction AreaUnit="SquareMiles"
DisplayTotals="True"
DistanceUnit="Miles"
MapUnits="Meters"
MeasureMode="Polyline"
FillSymbol="{StaticResource DefaultFillSymbol}"
TargetName="Map"/>My base layer is the ubiquitous world street map layer: http://services.arcgisonline.com/ArcGIS/rest/services/World_Street_Map/MapServer. Any pointers in the right direction would be greatly appreciated! Interestingly, the results I'm getting are the same as in the interactive SDK - the sample must be incorrect? Additionally, I can return correct results using the 'Line Lengths' sample, but that includes a bit of code, compared to the simple XAML declaration for the MeasureAction sample. Obviously, I'd prefer less code, but it is nice to know I have a viable backup.
