Hi,
I have an application with multiple layers coming from an ArcGIS Rest Service. I recently added a layer to the source mxd and republished the service. When I opened my Silverlight map application, all my existing layers were showing the wrong symbology and attribute information. I took a closer look and it seems like whenever layer order is changed, the existing layers in my map application will break. Does this mean that everytime I add or remove a layer I have to recreate my map application from scratch? This is extremely time consuming for applications that have many layers especially since we have so many applications.
