Gets the expiration date of the MediaLicense class instance.
Assembly: System.Windows (in System.Windows.dll)
If the MediaLicense instance represents a license chain, (root license plus leaf license) then it is the aggregate expiration of the chain. If the instance represents just a single license then it is the ExpirationDate of that license. Note that ExpirationDate is affected by all of the expiration policies in the license or license chain. For more information about license chains and leaf licenses, see Digital Rights Management (DRM).
