title: Where is Microsoft.AspNet.Identity.Owin.AuthenticationManager in Asp.Net Identity RTM version?
body: <p>I have installed the nightly build of the AspNet-identity assemblies from <a href="http://www.myget.org/f/aspnetwebstacknightly/" rel="noreferrer" title="aspnetwebstacknightly">here</a></p>
  
  <p>It seems that the <code>AuthenticationManager</code> class from the RC version is gone from the RTM version (<em>Microsoft.AspNet.Identity.Owin.1.0.0-rtm-130914</em>).</p>
  
  <p>It used to be in the <em>Microsoft.AspNet.Identity.Owin</em> assembly, but its no longer there.</p>
  
  <p>This class had the methods: <code>SignInAsync</code> and <code>CheckPasswordAndSignInAsync</code> that are used in the default project you get when creating new ASP.Net web application MVC project with Individual User Account authentication.</p>
  
  <p>Where is the AuthenticationManager now? Or what to use instead?</p>
