Hello Everyone ,

That is my first expérience with the Tracking Application especially with arcgis Geoevent Processor

In Fact my Question is :how to get a coordinate of the mobile (Gps) do i need an application inside the Device or not ?

i am using arcgis APi for silverlight and arcgis Geoevent processor
Any help or orientation will be grateful for me beacause i am new.
