title: Are the EnterpriseLibrary.Caching components discontinued, and, if so, as of which library version?
body: <p>I'm looking at some old code that relies on</p>
  
  <pre><code>Microsoft.Practices.EnterpriseLibrary.Caching
  </code></pre>
  
  <p>As far as I can tell, the namespace doesn't exist in the latest version of the EnterpriseLibrary. Is this correct? If so, when did the components get discontinued?</p>
