When using an ASP.Net MVC4 site, it's very easy to add OAuth authentication with SimpleMembership.
OAuthWebSecurity.RegisterTwitterClient(consumerKey,consumerSecret);
When using Azure Mobile Services on a client device, it's very easy to add OAuth authentication.
await App.MobileService.LoginAsync(MobileServiceAuthenticationProvider.Twitter);
The problem is that these are two different data stores. I need to users to be able to register and/or login from either the app or the site. What is the best/easiest way to provide integrated OAuth authentication from devices and an ASP.Net site? Are there samples available?
