Gets a collection of hashed pseudo unique Base64 string values on a per domain and machine basis.
Assembly: System.Windows (in System.Windows.dll)
Values within the collection can be null but will remain constant in count.
The end user can opt out of providing these values to the application by disabling protected content playback in the Silverlight configuration dialog or by using the private mode of their browser; the collection will be null in these instances.
For a list of the operating systems and browsers that are supported by Silverlight, see Supported Operating Systems and Browsers.
