title: OpenID Discovery URL list
body: <p>I use DotNetOpenAuth in my Asp.Net application.</p>
  
  <p>I want to create a login page where user can choose among most common OpenID providers like google, yahoo...</p>
  
  <p>I'd like to have image buttons like SO login. </p>
  
  <p>1) Is there a best practice to achieve this? (Like a free/open asp.net control)</p>
  
  <p>2) Do you have a list of common Discovery URLS?</p>
  
  <ul>
  <li><a href="https://www.google.com/accounts/o8/id" rel="nofollow">https://www.google.com/accounts/o8/id</a> (google)</li>
  <li><a href="https://me.yahoo.com" rel="nofollow">https://me.yahoo.com</a> (yahoo)</li>
  <li>... </li>
  </ul>
  
  <p><strong>update</strong></p>
  
  <p>Just for info I've found also this:</p>
  
  <ul>
  <li><a href="http://code.google.com/p/socialauth-net/" rel="nofollow">socialauth-net</a></li>
  </ul>
