Final Release and Support Plan for the ArcGIS APIs / Viewers for Flex and Silverlight

Blog Post created by GLehner-esristaff Employee on Nov 10, 2014

The next release of each ArcGIS API and Viewer (for Flex and Silverlight) will be significant in that they are the last planned releases of two once-popular technologies. While technical support will be available for both APIs and viewers through June of 2016, maintenance of these products will be discontinued. Customers who develop with these products should begin exploring web solutions that are based on JavaScript or HTML5.

The Transition to JavaScript


Over the past year, Esri has focused on greatly expanding the capabilities and usability of the ArcGIS API for JavaScript, enabling developers to build powerful and expressive applications with minimal code. In addition, new JavaScript-based applications have been introduced that enable users to quickly create beautiful, responsive web applications without writing a single line of code. These include several new web application templates as well as the Web AppBuilder for ArcGIS, all available with ArcGIS Online and Portal for ArcGIS. Customers that have built applications using the ArcGIS Viewers for Flex and Silverlight can now leverage the Web AppBuilder to create fully-functional GIS apps that can be used on any device.


As the ArcGIS Flex and Silverlight products move from mature support to their end of life phase, our Support teams are available to help customers transition to JavaScript, explore the various apps and tools available for getting started, and answer any questions that may arise.
