title: Unable to access CreateAsync in User Manager
body: <p>I'm trying to use the new <code>Asp.Net Identity</code> system. I've searched this in asp.net site and able to find a tutorial <a href="http://www.asp.net/identity/overview/getting-started/introduction-to-aspnet-identity" rel="noreferrer">here</a>.</p>
  
  <p>I've created <code>Register</code> action and appropriate view for it. But Unable to code it further as I'm struck using <code>User Manager</code> in Identity System.</p>
  
  <p>To be precise, It's here.</p>
  
  <pre><code>var result = await UserManager.CreateAsync(user, register.Password);
  </code></pre>
  
  <p>The <code>UserManager</code> class throws an exception</p>
  
  <pre><code>Using the generic type 'Microsoft.AspNet.Identity.UserManager&lt;TUser,TKey&gt;' requires 2 type arguments    
  </code></pre>
  
  <p>My question is why did the author of the tutorial did not get any sort of exceptions ? Am I missing any dependencies ? </p>
  
  <p>It seems like the documentation is not so perfect in asp.net site as well.</p>
  
  <p>Any help would be appreciated.</p>
