Cross-thread error when using Bing

I am repeatedly getting the following error which crashes the whole IDE (VS2010). The error is usually caused when closing down a running debug session, but also is sporadically caused when loading the bing layer in Designer View.

System.UnauthorizedAccessException
[InvalidCrossThreadAccess]

Edit:

This is the only relevant code:

xmlns:esri="http://schemas.esri.com/arcgis/client/2009"
xmlns:bing="clr-namespace:ESRI.ArcGIS.Client.Bing;assembly=ESRI.ArcGIS.Client.Bing"

<esri:Map>
    <bing:TileLayer ID="BingLayerAerial" LayerStyle="AerialWithLabels" ServerType="Production" Token="XXXXXXXXXXXXX" />
</esri:Map>

Update:

This problem was happening while I had the map inside a Tab in a TabControl. I removed the TabControl and have not experienced the error since.
