How to get ExtendedMembershipProvider to work with ASP.NET MVC 4 and Custom Membership Provider?

Question

I have got a custom membership provider to work with ASP.NET MVC 4 but when i whant to use the OAuth logins like Facebook etc I'm getting an error:

To call this method, the "Membership.Provider" property must be an instance of "ExtendedMembershipProvider".

This happening when calling the function OAuthWebSecurity.Login in the ExternalLoginCallback actionresult.

I guess to get all to work I need a custom "ExtendedMembershipProvider" but I can not find any information about it, any ideas?

WebMatrix.WebData.ExtendedMembershipProvider class

Inherit your custom membership provider from it and implement all members you need.
