title: 'Resource.Dimension' does not contain a definition for
body: <p><strong>Visual Studio 2017 intellisense</strong> underline all dimension resources in my cs code with the error: <em><code>Resource.Dimension</code> does not contain a definition for...</em> </p>
  
  <p>Intellisense offer me only standard dimensions properties.</p>
  
  <p>File with my dimensions is placed in <code>Resources\values\dimens.xml</code>. </p>
  
  <p>This file has following content:</p>
  
  <pre><code> &lt;?xml version="1.0" encoding="utf-8" ?&gt;
  &lt;resources&gt;
    &lt;dimen name="main_text_item_size"&gt;17dp&lt;/dimen&gt;
  &lt;/resources&gt;
  </code></pre>
  
  <p>All others resources are okay and I can work with them without any problem.</p>
