Prerequisites for ArcGIS Server and ArcGIS Engine
Accela Silverlight GIS supports GIS services published to ArcGIS for Server. To integrate with Accela Silverlight GIS, you must purchase a license for one of the aforementioned ArcGIS Server versions.
Additionally, you must publish a map service. ArcGIS Server hosts the map service for Civic Platform, Citizen Access, and online Mobile Office GIS functions. ArcGIS Engine hosts the map service for offline Mobile Office GIS functions.
If your agency integrates with ArcGIS Server services, you must also complete the ArcMap, ArcCatalog, ArcSDE, MXD, and ArcGIS Server prerequisites described in the Accela Silverlight GIS for ArcGIS Server Configuration Guide.
