title: When should HttpContext.User.Identity.IsAuthenticated and SignInManager.IsSignedIn(HttpContext.User) be used?
body: <p>There seems to be some ambiguity about these 2. I use them interchangeably throughout my project and the only reason is because I couldn't figure out when to use one or the other.</p>
  
  <p>What would be the cases where one is true while the other one isn't?</p>
  
  <p>If I were to only use ASP.NET Identity to authenticate users, would one or the other more favourable or it doesn't really matter?</p>
