I have private property to access AuthenticationManager:
private IAuthenticationManager AuthenticationManager => HttpContext.GetOwinContext().Authentication;
I want to mock the method GetExternalLoginInfoAsync() in order to receive fake ExternalLoginInfo object:
ExternalLoginInfo loginInfo = await AuthenticationManager.GetExternalLoginInfoAsync();
Both GetOwinContext() and GetExternalLoginInfoAsync() methods are extension methods. Is it possible to see source code of these methods to see how they works?
