asp.net mvc 3 unobtrusive client side validation not working in ie

        rel="stylesheet" type="text/css" />
    <script src="http://ajax.googleapis.co开发者_StackOverflow中文版m/ajax/libs/jquery/1.6.2/jquery.js" type="text/javascript"></script>

    <script src="//ajax.aspnetcdn.com/ajax/mvc/3.0/jquery.validate.unobtrusive.min.js"
        type="text/javascript"></script>

I am using data annotations to display the error message. In Firefox its working fine, but in IE its not displaying the error message in the client side. from the below link JQuery 1.6 $('form').validate() not working in IE7 & IE8, I came to see that

Jquery Validate does not currently work with jQuery 1.6 in IE6, IE7, and IE8.

I am using jquery UI autocomplete,Datepicker in my project. So if i change the jquery version from 1.6.2 to jquery 1.5.2 my validation works fine, but my autocomplete starts failing.

how to solve this? any thoughts?

jQuery.validate 1.8.1 is release for 2001 may to be resolve this problem for ie, I integrated with my MVC 3 project with client side validation and it works perfect for me.
