Version 3.1 of the ArcGIS API for Silverlight and ArcGIS Viewer for Silverlight now available!

The next version of the ArcGIS Viewer for Silverlight and award-winning ArcGIS API for Silverlight are now available for download.  We’ve worked hard over the last six months to improve both products by fixing issues, adding new capabilities, and aligning their release schedules.  A few of the additions in this release include:

API Enhancements

  • Support for the ArcGIS Online World Geocoding Service allows you to easily search for points of interest, filtering by proximity to input locations.  The service provides detailed information about results, including the distance from the search location and the type of location found.
  • Expanded support for the ArcGIS Portal REST API provides hooks to manage and get information about groups, sharing, and tags.
  • The new ArcGISWebClient class allows you to easily create and manage raw web requests that are optimized for ArcGIS Server, ArcGIS Online, and Portal for ArcGIS.
  • A CsvLayer data source has been added to facilitate showing CSV data on the map quickly and easily.

Viewer Enhancements

  • The new Query Related Records tool allows you to view a feature’s related records with the click of a button.  Developers can also download the tool’s source code from
  • You can now easily access secure services from ArcGIS Server and ArcGIS Online by signing in with a user name and password.
  • Support for ownership-based access of feature services allows service administrators to manage the viewing and editing of features based on user identity.  The Viewer’s editing tools now automatically honor the service’s configuration.
  • Support for editor tracking allows you to see who created a feature and edited it last.  If editor tracking is enabled on a feature service, the Viewer will automatically populate this information.

Also at version 3.1, both the API and the Viewer provide integration with Visual Studio 2012 (in addition to Visual Studio 2010) and support for Windows 8.  You can find out more details about what’s new in the API here and what’s new in the Viewer here.

    Hi Rick, Thanks for this and great that the source for the Query Related Records tool is available. It would be very useful to have access to the source for the other tools that come with the viewer (e.g. the Identify tool) – are these source files available?
    Many Thanks, Graham
