I am currently using ArcGIS Viewer for Silverlight to develop web applications. All application developed so far are very nice and accessible on our intranet. The problem emerged now is during   we access the applications on internet. Though I have both a client access and a cross domain at my root (???\wwwroot ) doesn???t access the services we have on our GIS server except the base map from ESRI.
Any body with solution?
I thank you !!!
