Gets or sets a Uniform Resource Identifier (URI) value that overrides whatever the license server URI is in the content header.
Assembly: System.Windows (in System.Windows.dll)
If the LicenseAcquirer is created on demand (from the media element) and if the property is null, the system uses whatever license server URI is in the content. For Windows Media DRM content and PlayReady content where the header does not have a license server URI, the AcquiringLicense step fails (see Digital Rights Management (DRM) for more information about how DRM with Silverlight works). In this case, you need to provide a URI to the correct Licensing Server using this property.
The URI only needs to be non-null at the time of callback into the base OnAcquireLicense method. Therefore, if you overloaded OnAcquireLicense and you call the base implementation passing in a URI (but the URI set to the LicenseAcquirer instance is still null) then it would succeed.
If set, the value of this property is passed as the licenseServerUri parameter of the OnAcquireLicense method.
