title: ASP.NET Identity - how to get all roles and how to delete a role?
body: <p>I am using Asp.net Identity with Web Forms in VS 2013 Express for Web.
  I am referring to this AspIdentitySample example at <a href="https://github.com/rustd/AspnetIdentitySample" rel="nofollow">https://github.com/rustd/AspnetIdentitySample</a>
  The example is with MVC.
  To get all roles and to delete a role, they use:</p>
  
  <pre><code>RoleManager.Roles()
  RoleManager.DeleteAsync()
  </code></pre>
  
  <p>But I cannot find these two methods in my RoleManager - I mean they don't appear in Intellisense at all.
  Are they only available in MVC, but not in Web Forms?</p>
  
  <p>I am very frustrated with this Asp.net Identity stuff, is there any ASP.NET Identity books so that I can learn?</p>
