“Muggle-born have no access to go inside the chamber of secret Harry, and only a heir of Slytherin can open the chamber. Since he is already here, the chamber of secret, has already been opened.” As you have guessed already, lines said by Albus Dumbledore to Harry Potter. Wonder why Harry Potter? Actually, our Silverlight is very much similar to that of Hogwarts. In case of authentication, I guess, to be precise. Silverlight provide the facility to authenticate the user using a particular query, making sure whether the querying user has the access to use the query or not. Just like you have to authenticate yourself, before the door of any house in Hogwarts, while requesting it to open. If you are not authenticated, your request will be rejected. In silverlight however, you have to authenticate yourself at the very beginning of the application, through a process we call as, Sign in.
