title: Get the username in Forms authentication
body: <p>I'm using Forms authentication.</p>
  
  <p>In Windows Authentication for get the user name of the PC i use: <code>User.Identity.Name</code></p>
  
  <p>I need this information also in Forms authentication but <code>User.Identity.Name</code> doesn't work.</p>
  
  <p>How can I get the User.Identity.Name without using Windows authentication?</p>
