Resource Page Description
Optional add-on for Silverlight.js. Adds Silverlight.supportedUserAgent function which determines if the user's browser is supported by Silverlight.

This functionality is not included in the Silverlight.js file because supportedUserAgent is highly dependant on current Web browser implementations. Because browsers evolve very quickly, this function will need to be updated much more frequently then the Silverlight.js file. If you need the functionality of Silverlight.supportedUserAgent then please check back often for updates to this file.

Current Release: 5.0.61118.0

This release is compatible with Silverlight 1-5.

  • userAgent [string]: optional. User Agent string to be analized. If null then the current browsers user agent string will be used.

Silverlight.js

This file can be used stand-alone or in conjunction with Silverlight.js.

It's unfortunate that this script returns unsupported for Google Chrome and Safari on Windows, when both browsers seem to run Silverlight 2 content just fine.

While Silverlight 2 is not OFFICIALLY supported in Chrome and Safari on Windows. When redirected to the Silverlight site and the user is shown the warning that their browser is unsupported. The download button should still be made to be visible and vocal instead of making the user think that there is no way to get Silverlight running on their browser.

Chrome and the Windows version of Safari share a Silverlight incompatibility that makes them unusable with some of my Silverlight applications. For a description and demo, visit http://www.nevlab.com/PluginResizeTest.htm

Safari 4 for Windows appears to fix the problem mentioned above, but Chrome still has the bug. Presumably Chrome's problem will disappear when it updates to the latest version of WebKit. A demo of the issue is at http://www.nevlab.com/PluginResizeTest.htm

The Chrome problem has disappeared; Neville's Resize Test is passed now. (WFM).
And yet Chrome is still officially unsupported. Perhaps a refrain of the old, well documented tale about MS putting spurious error messages into Windows just to make DR-DOS look bad?
Certainly, Chrome is eating away at IE market share!

There is no problem with Chrome 13. But this file is one year old, so useless ...

version [string] . Acceptable values also include "3.0", "4.0" and "5.0"

Note: The silverlight installation experience white paper here http://go.microsoft.com/fwlink/?LinkId=153361 contains templates that call Silverlight.supportedUserAgent() without parameters, the version parameter is now required and you need to update the templates e.g. Silverlight.supportedUserAgent('5.0', null) for this function to work.
