title: OperationContextScope with web reference
body: <p>Using a <code>service reference</code> i have this:</p>
  
  <pre><code>using (OperationContextScope scope = new OperationContextScope(client.InnerChannel)) {
      OperationContext.Current.OutgoingMessageProperties[HttpRequestMessageProperty.Name] = httpDetails;
      return predicate(client);
  }
  </code></pre>
  
  <p>I want to know how can i do the same with a <strong>web reference</strong> instead of <strong>service reference</strong>. Using web reference the property <code>InnerChannel</code> doesn't exist.</p>
  
  <p>There is some way to do that?</p>
