title: How do you show validation errors returned from WebAPI?
body: <p>I am using latest version of angular.js and WebAPI &amp; bootstrap.</p>
  <p>Imagine a form with few textboxes &amp; submit button. Once a user submits the form, data is validated by WebAPI call on server as we cant trust client side validations.</p>
  <p>In API controller, we do all our business validations.
  Assuming that data entered in all the textboxes are invalid:</p>
  <ol>
  <li><p>How should i return error message from my WebAPI so that the form displays it properly ?</p>
  <p>In normal MVC way without angular, this is easy. We can add errors to ModelState and the view will pick it and show the errors properly.</p>
  </li>
  </ol>
