title: Resharper add well-known types to import type
body: <p>Resharper has a very useful feature - import type even if dll is not added. For example i'm typing <code>var obj = new Graphics()</code> , R# suggests <code>Reference System.Drawing and use System.Drawing.Graphics</code>. But it works with few preconfigured namespaces only. </p>
  
  <p>I'm creating a lot of project that uses some extra libs, for example <code>System.Net.Http</code> or <code>System.Management</code>. I'm looking for a solution: how can I add these namespace to source where R# is looking for a reference resolution? I googled it but found nothing.</p>
