The following line is throwing an "Invalid response" error when called:
RouteTask rt = await RouteTask.CreateAsync(new Uri("http://mapcache.friscotexas.gov/arcgis/rest/services/RoadNetwork/NAServer/Route"));
I am using the release version WPF 100.
The routing service is currently working with my Silverlight application. It is running on version 10.3.1. It is not secured. I assume there is a problem with the service configuration or perhaps it being an older version but I haven't found any specific requirements. Any thoughts?
