Openid, OAuth and Windows Identity Foundation
There should be native providers for OpenID/OAuth/WIF so that users can easily implement authentication without much of an hassle, nowadays authentication can easily be delegated to a third party authentication server instead of creating my own login forms and stuff
Starting with VS 2013, you can create apps which can these providers. Please see http://www.asp.net/visual-studio/overview/2013/creating-web-projects-in-visual-studio#auth for the authentication options that are available.
In Visual Studio 2013, we added support for these external logins using the Microsoft OWIN components? Does that solve your request or were you looking for something else?
