title: user trimstart in entity framework query
body: <p>How can I use trimstart so entity framework will understand what to do?</p>
  
  <p>Here is my query:</p>
  
  <pre><code>string number="123";
  Workers.Where(x =&gt; x.CompanyId == 8).Where(x =&gt; x.Number.TrimStart('0') == number);
  </code></pre>
  
  <p>How can I make this query work without the AsEnumerable (there are a lot of workers in company 8)?</p>
