Using a .net4 based dll from .net2 based app not working for website
<p>Given this reference:

<p>Is it possible to add a .net2/3.5 website (not a web project) project to this solution and make it work with the adapter? I've tried but no luck. I keep getting error:</p>

<blockquote>
  <p>Could not load file or assembly 'Net4Assembly' or one of its
  dependencies. This assembly is built by a runtime newer than the
  currently loaded runtime and cannot be loaded.</p>
