MVC3 requires unobtrusive validation if you want jquery validation

Reading all the new things about MVC3, it appeared to me they had all these options to 'not' enable Unobtrusive javascript.   Turns out you really have two choices.  You can use msajax style validation (regular or unobtrusive) or you can use jquery validation - unobtrusive style.

If you are like me, you have been doing jquery validation all along, using the alternative script MicrosoftMvcJQueryValidation.js provided by Microsoft futures library.   Well, there does not appear to be a 'new version' of that script and that no longer works.

So, if you currently use MVC2 and jquery validation - the first thing you need to do is turn on unobtrusive validation in your web.config:

  <add key="ClientValidationEnabled" value="true"/> 
  <add key="UnobtrusiveJavaScriptEnabled" value="true"/> 

And then replace your included script of MicrosoftMvcJqueryValidation.js with jquery.validate.unobtrusive.min.js.
