Microphone access in Silverlight via Flash and JavaScript

Silverlight is unquestionably a powerful tool for .NET application developers; using almost of all the same WPF skills,.NET developers can create rich internet applications (RIA) right out of the gate. However, Silverlight has no microphone/webcam support, and if you need this functionality in a cross-browser RIA, the common thinking is cross out Silverlight and pencil in Flash or Java.

While it’s true that you’ll need to dip into Flash or Java for microphone/webcam support (at least until Silverlight 3, and possibly not even then), there’s no reason you can’t take advantage of Silverlight as your base application host and selectively use Flash as necessary for Silverlight’s missing features. Then, using a JavaScript bridge, you can get these browser technologies communicating with each other fairly painlessly. This integrated solution is what we’re considering at Tutor.com when we add voice communication support to the Tutor.com Classroom, and this post will detail how to use Flash for microphone support inside a Silverlight application, where the button controlling the microphone on/off switch is in the Silverlight application.
