SignInChallengeHandler

The simplest way to use this component is to set the IdentityManager's ChallengeHandler to a new instance of the SignInChallengeHandler:

    IdentityManager.Current.ChallengeHandler = new SignInChallengeHandler();  

Note: SignInChallengeHandler is only available for Windows Desktop and Windows Phone. Windows Store includes a built-in authentication dialog common to the platform.
