title: Visual Studio 2015 ASP.NET identity with Web Forms (not ASP.NET MVC)
body: <p>I am trying to use ASP.NET Identity with a web form (NOT ASP.NET MVC). I want to use the user name to authenticate, not the email address. I have tried all the answers for this same issue with ASP.NET MVC, but I cannot get anything to work after hours of working on this.</p>
  
  <p>How do I do this?</p>
