title: How can I install an older version of a package via NuGet?
body: <p>I want to install an older version of a package (<code>Newtonsoft.Json</code>). But NuGet rolls back:</p>
  <pre><code>PM&gt; Install-Package Newtonsoft.Json -Version 4.0.5
  Successfully installed 'Newtonsoft.Json 4.0.5'.
  Install failed. Rolling back...
  Install-Package : Already referencing a newer version of 'Newtonsoft.Json'.
  </code></pre>
  <p>How can I do it?</p>
