when I have a map with just a single WmsLayer added in XAML, the layer is not displayed. I've tried to set the map's spatial reference by explicitly settings the map's extent to an envelope with the correct spatial reference in XAML, but it has no effect.
But if I add another non-WMS layer to the map in XAML, under or above the WmsLayer, the WmsLayer is displayed.
I'm using version 2.4 of the Silverlight API version.
How can I display just a single WmsLayer in a map?
