Hi There;I would like to implement the behaviours and actions in silverlight. Here are the codes.the code is also here: http://help.arcgis.com/en/webapi/silverlight/samples/start.htm#ConstrainExtentBehavior
<UserControl x:Class="ArcGISMapping.behavioursandactions.ConstraintExtendBehaviour"

mc:Ignorable="d"
d:DesignHeight="300" d:DesignWidth="400"
xmlns:esri="http://schemas.esri.com/arcgis/client/2009"
xmlns:i="http://schemas.microsoft.com/expression/2010/interactivity">
<Grid x:Name="LayoutRoot" >
<esri:Map x:Name="MyMap" WrapAround="True" Extent="-15000000,2000000,-7000000,8000000">
<esri:ArcGISTiledMapServiceLayer ID="MyBaseLayer"
Url="http://services.arcgisonline.com/ArcGIS/rest/services/World_Street_Map/MapServer" />
<i:Interaction.Behaviors>
<esri:ConstrainExtentBehavior ConstrainedExtent="-15000000,2000000,-7000000,8000000" />
</i:Interaction.Behaviors>
</esri:Map>
</Grid>
</UserControl>
I am getting the error: The name "Interaction" does not exist in the namespace "http://schemas.microsoft.com/expression/2010/interactivity".How can I resolve that problem? Thanks in advance.
