title: Using System.Device in an MVC project
body: <p>This doesn't seem to make sense.</p>
  
  <p>I'm trying to use the System.Device library in a project to take advantage of the geo location functionality. I'm adding code to a Razor page as I usually do.</p>
  
  <p>I have a reference to the library and I've added the using to the top of the razor view:</p>
  
  <pre><code>@using System.Device;
  </code></pre>
  
  <p>Device has a red underline because it cannot be found. Typing <code>System.D</code> does not yield <code>Device</code> in intellisense. This doesn't seem to make sense as the library is <em>definitely</em> referenced.</p>
  
  <p>The web.config is in Views has no mention of <code>System.Device</code>. If I do a full search of the solution for 'device' there are no mentions of it anywhere I wouldn't expect.</p>
  
  <p>I've open and closed files, removed the reference, restarted VS, restarted my computer. Everything. It still persists.</p>
  
  <p>I feel like either there's something I don't know or I'm doing something stupid. Am I missing something here?</p>
