Add geoprocessing tasks

The ArcGIS Viewer for Silverlight provides you with the ability to interactively create tools that will execute geoprocessing tasks. If you are unfamiliar with geoprocessing, see the What is geoprocessing? topic. When you execute a task in a geoprocessing service, it executes on the server rather than using resources of the client machine where the Viewer is being used. For more information, see An overview of geoprocessing with ArcGIS Server.
