title: Server.MapPath does not exist in current context
body: <p>Inside my MVC4 project I have the namespace</p>
  
  <blockquote>
    <p>prj.MVC4.Controllers </p>
  </blockquote>
  
  <p>where I'm using <code>Server.MapPath(..)</code> without problem and on </p>
  
  <blockquote>
    <p>prj.MVC4.Models</p>
  </blockquote>
  
  <p><code>Server.MapPath(...)</code> does not exist on current context.</p>
  
  <p>I'm aware that <code>Server.MapPath</code> resides in <code>System.Web</code> and both namespace and assembly are added into class with using <code>System.Web</code> and <code>System.Web.dll</code> is added to the prj.</p>
  
  <p>on <kbd>Ctrl</kbd> + <kbd>.</kbd>. I'm getting  <code>Microsoft.SqlServer</code> as suggested namespace to add.</p>
  
  <p>How to fix this?</p>
