Unable to proceed to Login via OpenID

Hello.

I used this tutorial to create a ASP.NET MVC 5 App with Facebook, Twitter, LinkedIn and Google OAuth2 Sign-on.

I created two apps, one on google, another on facebook. I think those parts are ok.

The problem is i get null value for "var loginInfo = await AuthenticationManager.GetExternalLoginInfoAsync();" in AccountController, in the "ExternalLoginCallback" method.

What is the solution for my project ?

Thanks :)
