I am following this example: OpenID Authentication with ASP.NET MVC3 , DotNetOpenAuth and OpenID-Selector
I started a new MVC4 project and add the OpenId code as suggested in the article above.
A break point on the Authenticate action in AccountController is unreachable.
Clicking on Google or Yahoo takes me to this blank page: http://localhost:37638/Account/Authenticate?ReturnUrl=
