title: Bubble a failed request validation to a controller in MVC
body: <p>I don't want to disable validation, however it would be great to display a message to a user. Whilst I think it is highly unlikely that a user will ever have a legitimate need to include &amp;# in a text field, I can see someone typing in a free text field something starting with a &lt;.</p>
  
  <p>Is there a way to detect that a validation exception would be thrown and instead display it as a validation message?</p>
