body: <p>what is difference anyasync and where in linq?
  Is this same <code>Where(pr =&gt; pr.RegistoId == registoId &amp;&amp; pr.HoraFim == null)</code> ?</p>
  <pre><code>public async Task&lt;bool&gt; IsParagemOnGoingAsync(int registoId)
      {
         return await _context.ParagensRegistos
             .Where(pr =&gt; pr.RegistoId == registoId)
             .AnyAsync(pr =&gt; pr.HoraFim == null);
      }
  </code></pre>
