ASP.NET MVC3 Client validation not working after jQuery update

[samfolg]

I am running a project in MVC3 which was using jQuery 1.5.1 . We recently had to move to jQuery 1.8.3, however now the client-side validation is not working anymore.I tried the solution at JQuery 1.5 breaks Compare Validate (JQuery Validate 1.8) however it is not working. I tried to remove the jquery.validate.unobstrusive.js from my layout and I realized that the client validation was still working if I had the default jQuery 1.5.1 instead of the jQuery 1.8.3, which means the validation must be done somewhere in the default jQuery 1.5.1 of MVC3.EDIT The problem seems to come from jquery.validate.unobtrusive.min.js since when I removed it, even the old jQuery stopped working.If someone could help me fix this, it would be much appreciated.Thanks
