ASP.NET 4+ / VS2010 MVC skeleton / Yahoo Open ID

I need a skeleton web application using asp.Net 4.0 C# / vs2010 (or 2012) using MVC. The user will use Yahoo Open ID (OAuth) to log in to the site. After login the display a new page that contains an iframe or such that will be directed to skedge.me. The first time the user logs in you will need to handle the Oauth flow for Yahoo OpenID. The user should not need to grant yahoo access after the initial login. For starters you can store the necessary access data in a file (or DB). Note you will need to keep the session handle since the access token/secret expires every hour. [login to view URL] please code this for multiple login times for further extension of the project (possibly facebook and google) and native login (no OpenID). No one should be able to get to any page if not logged in.
