At runtime the certificate that has been installed on a local device and registered from Azure Access Control will be assigned to the instance of this class. The type of the ServiceCredentials class must be specified when you instantiate a service host instance and an instance of the UserRegisterServiceCredentials class needs to be added to the host behaviors collection after the host has been instantiated. The responsibility of the class UserRegisterTokenAuthenticator is to communicate to the Access Control Service to validate the security token for authentication. This class is used by the UserRegisterSecurityTokenManager class. Listing 5-13.
