It seems that you have to write your own custom provider. If so, you should look at http://blogs.msdn.com/b/webdev/archive/2012/08/23/plugging-custom-oauth-openid-providers.aspx and http://blog.mrroa.com/post/30454808112/asp-net-custom-linkedin-oauth-provider

What I do is : In AccountController : - I add using Facebook; (facebook.dll from www.csharpsdk.org) also in AccountController, find in ExternalLoginCallback:

Here, i use the facebook c# sdk to ask for extra permissions before invoking CreateOrUpdateAccount.

I don't think this is the best solution but it works.
