Remarks

The properties of CaptureDevice are mainly used to determine how that device is represented in the Silverlight configuration dialog box on the Webcam / Mic tab. Other properties that are more specific to working with captured data as part of a sink implementation are instead declared on either AudioCaptureDevice or VideoCaptureDevice.

Example scenarios for using CaptureDevice properties include prompting users to change either audio or video devices in their configuration UI. You might prompt the user to change settings if there are alternatives reported by GetAvailableAudioCaptureDevices or GetAvailableVideoCaptureDevices that would work, for cases where the current default device (GetDefaultAudioCaptureDevice, GetDefaultVideoCaptureDevice) is not supported. You can also display strings in the UI, for example, a button with localizable text "Capture video from * device" where * is the FriendlyName.
