NA Route Rest services gives error

[MuhammadWaqar_ul_islam]

I have create Na Routing  sample to test
on arcgis info its works fine create route on the data
but when i create Network Analysis services through Arcgis server and  using rest services in silverlight sample
http://help.arcgis.com/en/webapi/silverlight/3.0/samples/start.htm#Routing
its gives error
Black"Routing error: Unable to complete operation unable to find atribute invalid Context" my rest services

i Have discuss this topic on arcgis silverlight forum one of esri person forward me to this forum

Muhammad,

From your previous message it looks like you have already gotten a valid route back from the server.

The only step is left is to make your Silverlight application send the same HTTP parameters to the server endpoint: use RouteTask, RouteParameters, and RouteResult classes from the ESRI.ArcGIS.Client.Tasks namespace.
Here is a good sample how to use route endpoint in Silverlight: http://help.arcgis.com/en/webapi/silverlight/samples/start.htm#Routing
