Hi,
We seem to get repeatable errors when zooming in and out of the map rapidly. We use an ArcGISTiledMapService layer as our background but when the opacity is changed from the default we seem to get unrecoverable errors on the WPF render thread (partial stack trace below). Also, with opacity set to 1.0 we get similar issues if the user rapidly clicks through the buttons in the navigation widget (reset north and zoom to full extent). I notice that in the online SDK, the map can become unresponsive when doing this also. Are people aware of this and if so are there any steps we can take to alleviate or prevent this?
System.InvalidOperationException was unhandled
