Bing Map Tile Layer with Proxy

[NigelMacLucas1]

I have added a bing map layer to my app using a basic key from Microsoft

<bing:TileLayer ID="BingLayerAerial" LayerStyle="AerialWithLabels" Token="my key here"/>

When I start the app when I'm behind a proxy server I get an error

"ProtocolException was Unhandled"
"The remote server returned an unexpected response (417) Expectation Failed"

When I use the app on a network with no proxy required, it works fine.

If I comment the bing layer out and add some sample online content instead.

<esri:ArcGISTiledMapServiceLayer ID="StreetMapLayer"
                Url="http://services.arcgisonline.com/ArcGIS/rest/services/World_Street_Map/MapServer"/>
            <esri:ArcGISDynamicMapServiceLayer ID="DynamicLayer" Url="http://sampleserver3.arcgisonline.com/ArcGIS/rest/services/Earthquakes/RecentEarthquakesRendered/Map..."/>

Everything works fine, the app downloads all content no problem.

Are there special proxy settings for Bing Map Tile Layers?

I ran the Bing Map sample from the SDK Samples. Fails with the same error. Here is the crash dump

Sample: BingImagery

Hope this provides some help to diagnosing the problem
