How to Use Online IDs in Windows Phone Apps
Nick Randolph at BuildMobile has authored four comprehensive posts with code snippets about using several authentication models in Windows Phone apps.
- Windows Live ID
- This method allows you to authenticate a user and retrieve their profile from Windows Live.
- Facebook
- Facebook uses OAuth 2 to allow third party applications to authenticate and interact with Facebook data.
- Twitter
- Several social networking platforms like Twitter use OAuth 1 which is much more involved. Once the user has been authenticated, the application will have an Access Token which is used to access any of the Twitter APIs.
- You can start with the code that has been used for Twitter authentication.
