Version 3.2 of the ArcGIS API for Silverlight and ArcGIS Viewer for Silverlight now available!

New versions of the ArcGIS Viewer for Silverlight and ArcGIS API for Silverlight are now available for download.  For the 3.2 release, the development team has worked hard to implement key functionality and improve product quality.  Additions in the latest version include:

API Enhancements

  • New task-based methods greatly simplify asynchronous programming by enabling the use of the async and await keywords when making calls to ArcGIS services
  • Symbol rotation can be defined through use of the new RotationType and RotationExpression properties on renderers
  • A new WebMapViewModel eases the use of web maps in apps that follow the Model-View-ViewModel (MVVM) design pattern
  • Labels on dynamic layers in ArcGIS map services can be manipulated through new labelling objects
  • Enhancements to the IdentityManager add support for OAuth authentication workflows

Viewer Enhancements

  • A new tool for querying layers allows application designers to interactively define complex queries, while showing end-users a simple dialog consisting of labels, textboxes, and drop-down menus for inputting query values
  • Support for URL parameters allows users to specify initialization parameters such as extent, scale, web map, and place search by including them in the query string of a Viewer application’s URL
  • Enhancements to the Viewer’s pop-ups provide improved appearance, performance, and the ability to open pop-ups by tapping features on the map
  • Security additions allow using secure services that are federated with ArcGIS for Portal and connecting to ArcGIS for Portal instances that implement public-key infrastructure (PKI) or Integrated Windows Authentication (IWA) security

Additionally, the 3.2 releases of both the API and the Viewer provide integration with Visual Studio 2013 and support for Windows 8.1, Windows Server 2012, and Windows Server 2012 R2.  You can learn more about what’s new in the API here, and what’s new in the Viewer here.

    I had no problem downloading ArcGIS Viewer, but when I try to download the API for Silverlight it keeps sending me around in circles. I log into every prompt I encounter and still it does no good. Where are you hiding it?

    Even though the login gives me the option to use my ArcGIS Online account, it will not take me to the download section. I ended up having to create a completely separate ArcGIS for Developers account with its own username and password. What a pain.

    I am unable to download the 3.2 API because I don’t have a developer account and when I attempt to create on, I get a page that says “Error, We’re sorry, but your request could not be completed at this time. Please try again later.” this has been happening for a couple of weeks now.
