I've got a web forms application that i need to integrate Facebook, google and twitter log in but what I've found with all the tutorials is that my solution does not have Startup.auth.cs, and then when i implement a Owin class and try to call
app.UseCookieAuthentication
i get the error that owin.iappbuilder doesn't contain the definition.
I am using a 4.5 .net framework and do not have MVC so any help would be great.
I have been stuck on this error for quite some time so getting past this with help or a direction to a tutorial will be a great relief
