Silverlight 4 WebCam - a quick glance
WebCam support in Silverlight 4 is a much anticipated feature, and probably didn’t come as much of a surprise.  It’s relatively simple to enable this feature.  The below example shows a simple UI with the code to enable the webcam.  This post does not cover multiple webcams, however calling CaptureDeviceConfiguration.GetAvailableVideoCaptureDevices returns a list of all available webcams. First create a simple UI (a Rectangle and a Button).

Changing your default WebCam & Mic – Silverlight 4
Webcam and microphone support are a much anticipated feature to Silverlight 4.  If you have more than one webcam or audio input device, it’s possible to change your default device. Right click on your application > Click Silverlight > Webcam/ Mic.  Here you will find a menu where you can choose your default devices.

NotificationWindow – Silverlight 4
A new addition to Silverlight 4 is the NotificationWindow.  This type of window enables you to show a System notification much like when you receive an Outlook new mail notification or a Growl notification in OSX. Since it operates like a system message, this feature is only available in Out of Browser (OOB) scenarios. This example shows how to instantiate a NotificationWindow, with the resulting application like the below screenshot.

Silverlight 4 – new features
When Silverlight 3 debuted at MIX09, there were a number of places to find information about the new features, so better than others.  Unfortunately I never remembered the sites and always relied on Google to produce the site for me.  This time will be different; this post will serve as my place for SL4 info.

Check if running in Out of Browser - Silverlight
