A while ago I posted about BrowserHawk adding support for Silverlight detection and for a while, apart from writing your own code, that had been it.
The good news is that as Silverlight is getting more popular the options are improving… I got a comment on the post to let me know that BrowserObject now also supports Silverlight detection in the same way as other plug ins.
The free version doesn’t detect plugins, but does give you some basic information for very little effort. The upscale product works for both .Net and PHP infrastructure and comes with some easy getting started samples to make you productive.
Good to see the eco-system growing.
