Currently, there are two Viewer types for Geocortex. Most Ruekert-Mielke clients have the Geocortex Silverlight Viewer (Desktop Viewer or Classic Map). Many clients also have the Geocortex HTML5 Viewer (Mobile Viewer or GIS Map). In the coming months there will be some major changes to Google Chrome which will start forcing a shift away from using the Silverlight Viewer.
Google first announced their plan to stop support for Silverlight in their Chrome web browser last year, but set no definite date that support would no longer be available. Support for Silverlight inside Chrome saw deprecation in January 2015, with workarounds ending this April.
In January, Google released a version of Chrome that prompts users to enable Silverlight when accessing a Silverlight application. Once enabled, the setting should stay indefinitely and users won’t be asked again.
In April of 2015, Google will roll out another update that disables Silverlight from running in Chrome entirely. At this point, it will be technically possible to override this behavior in Chrome’s settings, but the average user will be unable to do this.
In September of 2015, Chrome will completely lose the ability to run Silverlight with no way to override. While the September date gives a sliver of hope for running Silverlight applications on Chrome later into 2015, our advice is to start moving away from the Silverlight Viewer.
There will be some differences between Silverlight and HTML5 as we are still working on bridging the gap between the two platforms. In the coming months we expect to make more updates to help bring more functionality into the HTML5 Viewer.
