title: jQuery 1.7.1 Breaks Unobtrusive Validation?
body: <p>With VS2010's default MVC3 project template, jQuery version is 1.5.1 and it works fine to support Unobtrusive Validation.</p>
  
  <p>Today I downloaded jQuery 1.7.1 to replace 1.5.1 and Unobtrusive Validation stopped working. The JS files I have in my project are:</p>
  
  <ul>
  <li>jquery-1.5.1.min.js/jquery-1.7.1.min.js</li>
  <li>jquery.validate.min.js</li>
  <li>jquery.validate.unobtrusive.min.js</li>
  </ul>
  
  <p>I deleted all other JS files.</p>
  
  <p>The only difference in my code is to choose different version of jQuery.</p>
  
  <p>Anybody else experienced same issue?</p>
