I created a new ArcGIS Runtime for WPF application. I then went into Blend and added a StackPanel with a nice transition between hidden and shown. Back in Visual Studio 2012, I can run the application and everything works fine. However, if I try to add the ConstrainExtentBehaviour to the map, I get the following error:The name "ConstrainExtentBehavior" does not exist in the namespace "http://schemas.esri.com/arcgis/client/2009"The full XAML code is below.Is it possible that there's a name conflict between the ArcGIS schema and one of the Expression schemas?Thanks,Jon.<Window xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:esri="http://schemas.esri.com/arcgis/client/2009" xmlns:i="http://schemas.microsoft.com/expression/2010/interactivity" xmlns:ei="http://schemas.microsoft.com/expression/2010/interactions" x:Class="ArcGISWpfApplication2.MainWindow" Title="MainWindow" Height="350" Width="525"> <Grid x:Name="grid"> <VisualStateManager.VisualStateGroups> <VisualStateGroup x:Name="VisualStateGroup"> <VisualStateGroup.Transitions> <VisualTransition GeneratedDuration="0:0:0.3"/> </VisualStateGroup.Transitions> <VisualState x:Name="Hidden"/> <VisualState x:Name="Visible"> <Storyboard> <DoubleAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.RenderTransform).(TransformGroup.Children)[3].(TranslateTransform.Y)" Storyboard.TargetName="stackPanel"> <EasingDoubleKeyFrame KeyTime="0" Value="-95"/> </DoubleAnimationUsingKeyFrames> <ColorAnimationUsingKeyFrames Storyboard.TargetProperty="(Panel.Background).(SolidColorBrush.Color)" Storyboard.TargetName="stackPanel"> <EasingColorKeyFrame KeyTime="0" Value="#7F000000"/> </ColorAnimationUsingKeyFrames> </Storyboard> </VisualState> </VisualStateGroup> </VisualStateManager.VisualStateGroups> <esri:Map x:Name="_map" UseAcceleratedDisplay="False"> <i:Interaction.Behaviors> <esri:ConstrainExtentBehavior ConstrainedExtent="-20037508.3427892,-20037508.3427892,20037508.3427892,20037508.3427892" /> </i:Interaction.Behaviors> <esri:ArcGISTiledMapServiceLayer ID="World Topo Map" Url="http://services.arcgisonline.com/ArcGIS/rest/services/World_Topo_Map/MapServer"/> </esri:Map> <StackPanel x:Name="stackPanel" HorizontalAlignment="Left" Height="110" Margin="0,209,0,-95" VerticalAlignment="Bottom" Width="{Binding ActualWidth, ElementName=grid}" Background="#00000000" RenderTransformOrigin="0.5,0.5"> <StackPanel.RenderTransform> <TransformGroup> <ScaleTransform/> <SkewTransform/> <RotateTransform/> <TranslateTransform/> </TransformGroup> </StackPanel.RenderTransform> <i:Interaction.Triggers> <i:EventTrigger EventName="MouseEnter"> <ei:GoToStateAction StateName="Visible"/> </i:EventTrigger> <i:EventTrigger EventName="MouseLeave"> <ei:GoToStateAction StateName="Hidden"/> </i:EventTrigger> </i:Interaction.Triggers> </StackPanel> </Grid> </Window>
