You can improve the security of your Windows Store app using the authentication and cryptography capabilities provided by the Windows Runtime. You can use the different authentication APIs to verify the identity of a user as well as verify user consent for purchases or other actions. You can use the cryptography APIs to secure data and resources and verify trust relationships through encryption and digital signatures. For more information, see Securing apps.
Managing user contacts
Apps can also work with user contacts using the Windows.ApplicationModel.Contacts and Windows.ApplicationModel.Contacts.Provider namespaces. When working with contacts, apps can choose to get contact information from other apps, such as Live, or to provide contacts to other apps. For more information, see Managing user contacts.
