Yesterday I shared all the NuGet packages we’re building to make it easy to build Windows Phone and Windows Azure applications. Today I wanted to share how easy it is to build a Windows Phone application that leverages the Windows Azure Access Control service.
The Phone.Identity.AccessControl.BasePage NuGet package includes a control for Window Phone that allows your phone applications to outsource user authentication to the Windows Azure Access Control service (ACS). This service enables your users to login by reusing their existing accounts from identity providers such as Windows Live ID, Google, Yahoo, Facebook, and even Active Directory.
