title: Update jQuery 1.8.3 to jQuery 1.9.0 in ASP.NET MVC 4
body: <p>we use ASP.NET MVC 4 and i update our project to use jQuery 1.9.0 from jQuery 1.8.3,
  BUT now Not work client scripts,like jQuery validation,jquery unobtrusive ajax and 3rd party jQuery library and etc!</p>
  
  <p>According to <a href="http://blog.jquery.com/2013/01/15/jquery-1-9-final-jquery-2-0-beta-migrate-final-released" rel="nofollow">http://blog.jquery.com/2013/01/15/jquery-1-9-final-jquery-2-0-beta-migrate-final-released</a> we must use <a href="https://github.com/jquery/jquery-migrate" rel="nofollow">jQuery Migrate Plugin</a>.we use Bundling in our MVC project,but when i use this plugin, jQuery.migrateWarnings not available in console!</p>
  
  <p>My Question:</p>
  
  <p>how we must update jQuery 1.8.3 to jQuery 1.9.0 without any problem in ASP.NET MVC 4 with Bundling enabled?</p>
