Bing TileLayer Silverlight 4

KadeSmith

When I try adding a Bing TileLayer to a map in SL4, I get the following error message:

A value of type 'TileLayer' cannot be added to a collection or dictionary of type 'LayerCollection'.

Exact code in SL3 is working fine.  Here are portions of my code.

xmlns:bing="clr-namespace:ESRI.ArcGIS.Client.Bing;assembly=ESRI.ArcGIS.Client.Bing"

<esri:Map x:Name="Map" IsLogoVisible="False" Loaded="Map_Loaded" Grid.Row="1">
            <esri:Map.Extent>
                <esriGeometry:Envelope XMin="-9860192.874701" YMin="3536523.562187" XMax="-9454281.630124" YMax="4181859.017432">
                    <esriGeometry:Envelope.SpatialReference>
                        <esriGeometry:SpatialReference WKID="102100" />
                    </esriGeometry:Envelope.SpatialReference>
                </esriGeometry:Envelope>
            </esri:Map.Extent>
           
            <esri:Map.Layers>
                <bing:TileLayer ID="BingLayer" LayerStyle="Road" Visible="True" />
                <esri:ArcGISTiledMapServiceLayer ID="Street Map" Url="http://server.arcgisonline.com/ArcGIS/rest/services/World_Street_Map/MapServer" Opacity=".5" />              
                <esri:GraphicsLayer ID="MarkupDrawingLayer" />
            </esri:Map.Layers>
           
        </esri:Map>

Thanks Dominique

private void RadioButtonOff_Click(object sender, RoutedEventArgs e)
        {
            ESRI.ArcGIS.Client.Bing.TileLayer tileLayer = MyMap.Layers["BingLayer"] as TileLayer;
            tileLayer.Visible = false;
        }

        private void RadioButton_Click(object sender, RoutedEventArgs e)
        {
            ESRI.ArcGIS.Client.Bing.TileLayer tileLayer = MyMap.Layers["BingLayer"] as TileLayer;
            string layerTypeTag = (string)((RadioButton)sender).Tag;
            TileLayer.LayerType newLayerType = (TileLayer.LayerType)System.Enum.Parse(typeof(TileLayer.LayerType), layerTypeTag, true);
            tileLayer.LayerStyle = newLayerType;

            if (tileLayer.Visible == false) 
            {
            tileLayer.Visible = true;
            }
 
        }

I tried that just after you posted and it works, rather than doing the code in xaml.

I assume I would have to contact microsoft or track the usage manually to find out if Bing Maps is still counting transactions because I am only changing the visibility of the tile layer, not removing the actual basemap.
