I am trying to upgrade to ESRI 3.1 Silverlight API.
I am suddently getting this error.. on the load of my map. It is happening after some my basemap has been loaded.
Application_UnhandledExceptionSystem.ArgumentNullException: Value cannot be null.\nParameter name: SpatialReference\n at ESRI.ArcGIS.Client.Utils.Normalization.Normalize(Geometry g)\n at ESRI.ArcGIS.Client.Geometry.Geometry.NormalizeCentralMeridian(Geometry g)\n at ESRI.ArcGIS.Client.LayerCanvas.ClipBox(MapPoint origin, Double resolution, Boolean isWrapAround)\n at ESRI.ArcGIS.Client.Map.CheckClipBox()\n at ESRI.ArcGIS.Client.Map.<Map_SizeChanged>b__d()\n at ESRI.ArcGIS.Client.ThrottleTimer.<.ctor>b__1(Object s, EventArgs e)\n at MS.Internal.CoreInvokeHandler.InvokeEventHandler(UInt32 typeIndex, Delegate handlerDelegate, Object sender, Object args)\n at MS.Internal.JoltHelper.FireEvent(IntPtr unmanagedObj, IntPtr unmanagedObjArgs, Int32 argsTypeIndex, Int32 actualArgsTypeIndex, String eventName, UInt32 flags)
I tried removing my MapExtentChanged and MapSizeChanged events, but still the same error. (sometime after those events have been hit)
However, if I flip the wraparound property to False.. the error goes away, but that is obviously not a good option.
