I have created an Network Analyst Routing sample. On Arcmap it works fine when creating a route on the data.

However, when I create Network Analyst service through ArcGIS Server, using this REST service Silverlight sample gives this error:

Routing error: Unable to complete operation unable to find attribute invalid Context

Any help please.

Is the Network Analyst for ArcGIS Server extension licensed on your server? – Kirk Kuykendall Mar 29 '13 at 17:45
Sorry I didn't see your answer Yes the Network Analyst for ArcGIS Server extension is licensed, and finally I found a solution using Geoprocessing task. – Geomak Apr 1 '13 at 13:05

i have made a model using model builder like described here , then i published the model on arcgis server, before calling it using silverlight.

i have solved this problem using geoprocessing task – Geomak Apr 2 '13 at 15:19

come across and solved the problem just now
cause RouteParameters 's default value of UseHierarchy is True
just set UseHierarchy to False

RouteParameters parameters = new RouteParameters();
parameters.Stops = stopsGraphicsLayer;
parameters.OutSpatialReference = MyMap.SpatialReference;
parameters.UseHierarchy = false;
