Could you tell how it must work?
I see just Unauthorized exception (401) after i set ConsumerKey and ConsumerSecret in this example. I've check my application for access level so it is ok.
I loggined via PinAuthorizer and save credentials to check them on WinRTAuthorizer. With the last ones it works fine but how I can be authorized if I set just ConsumerKey and ConsumerSecret - no UserId, no email, password, pin?
