MVC3 breaks any manual use of jquery validate

If MVC client side validation using model attributes just would not do what you needed it to, you could always turn of client side validation and call validate yourself:

            rules: {
                myField: {
                    minlength: 5, maxlength: 5, required: true, digits: true
            submitHandler: function (form) {
                $.post($(form).attr("action"), $(form).serializeArray(), function (data) {
                return false;

Well, not anymore! MVC3 and jquery unobtrusive (which is become VERY obtrusive) validation breaks this, even if you disable client validation on this form!

Why? The jquery.validate.unobtrusive.js code calls form.validate() even if no rules were found or created - destroying whatever you had done! So, here is another fix to that code.  Simply add the one line, shown here on line 100.  Note this has my other MVC3 validates hidden fields using jquery validation fix
