How do I prevent StyleCop warning of a Hungarian notation when prefix is valid : <p>I have the following code:</p>

<pre><code>var fxRate = new FxRate();
</code></pre>

<p>which is giving me the following <a href="https://github.com/StyleCop/StyleCop.ReSharper" rel="noreferrer">StyleCop ReSharper</a> warning:</p>

<blockquote>
  <p>The variable name 'fxRate' begins with a prefix that looks like
  Hungarian notation.</p>
</blockquote>

<p>I have tried copying the Settings.StyleCop file to my solution folder and adding an entry for fx:</p>

<pre><code>  &lt;Analyzers&gt;
    &lt;Analyzer AnalyzerId="StyleCop.CSharp.NamingRules"&gt;
      &lt;AnalyzerSettings&gt;
        &lt;CollectionProperty Name="Hungarian"&gt;
          ...
          &lt;Value&gt;fx&lt;/Value&gt;
          ...
</code></pre>

<p>I've restarted VS but I still get the same warning.
I am using the StyleCop ReSharper extension in VS2017.</p>

<p>How do I ensure 'fx' is a valid prefix in the solution (for all team members)?</p>
