Silverlight not picking up changes made to mxd????

[AngelGonzalez]

I am using SL4 with ESRI 2.0 API.  I have a simple SL app with a TitledMapService and a DynamicMapService. When I first create the Map Services in ArcServer, which point to the mxds, I am able to see layers correctly in silverlight.  When I make any changes to the DynamicMapService mxd (ie add a new layer) ,restart the map service and then run the silverlight app. again the changes are not being picked by the silverlight app.  Now if I make a new Map Service pointing to the same mxd and modify the silverlight app to use this new service I am able to see the changes I made to the mxd. Also if you make changes to the mxd and re-boot ArcServer you can see the changes.

Why can't Silverlight see changes made to an mxd?

Note: I used ESRI sample SubLayer List to view the layers available.

Be aware that both the REST server and the browser can be doing some caching here.
Clear your REST cache (http://myserver/arcgis/rest/admin) after changing your service.
You can also disable the browser cache by setting DisableClientCache="True" on your dynamic layer.
