Passing data to activity from threaded service
How can I pass data from a threaded service to the activity that created the service?

It's a login scenario. The user enters credentials, the activity starts a service which calls an wcf service to confirm the credentials. When this is done I want the service to tell the activity that the login has succeeded/failed.
