title: Can't reference System.Web in a console App
body: <p>I need to use the HttpUtility in a console app like described in this question <a href="https://stackoverflow.com/questions/14731/urlencode-through-a-console-application">UrlEncode through a console application?</a></p>
  
  <p>The problem is that for some weird reason when I try to add a reference and go to .NET tab, I don't see System.web and also when I go to Recent and chose the System.Web, it adds the reference but with a yellow  exclamation mark.</p>
  
  <p>What is wrong, I know that this is a trivial thing...</p>
