Asp .NET Webforms is injecting code on WebResource.axd that I need to remove

I am trying to make a small WebForms app. However, I am having a huge problem because there is a code that is being inserted in the WebResource.axd file that is causing me problems.

However, I have no idea where this is happening. In addition to this web Forms is also injecting an old version of javascript that I no longer need.

Is there a way to disable WebResource.axd? If not where exactly is it getting the content from? I tried doing a global search but I could not find the code.

Here is the code that is causing me problems:

if (window.jQuery) {
    (function ($) {
        var dataValidationAttribute = "data-val",
            dataValidationSummaryAttribute = "data-valsummary",
            normalizedAttributes = { validationgroup: "validationGroup", focusonerror: "focusOnError" };
        function getAttributesWithPrefix(element, prefix) {
            var i,
                attribute,
                list = {},
                attributes = element.attributes,
                length = attributes.length,
                prefixLength = prefix.length;
            prefix = prefix.toLowerCase();
            for (i = 0; i < length; i++) {
                attribute = attributes[i];
                if (attribute.specified && attribute.name.substr(0, prefixLength).toLowerCase() === prefix) {
                    list[attribute.name.substr(prefixLength)] = attribute.value;
                }
            }
            return list;
        }
        function normalizeKey(key) {
            key = key.toLowerCase();
            return normalizedAttributes[key] === undefined ? key : normalizedAttributes[key];
        }
        function addValidationExpando(element) {
            var attributes = getAttributesWithPrefix(element, dataValidationAttribute + "-");
            $.each(attributes, function (key, value) {
                element[normalizeKey(key)] = value;
            });
        }
        function dispose(element) {
            var index = $.inArray(element, Page_Validators);
            if (index >= 0) {
                Page_Validators.splice(index, 1);
            }
        }

            normalizedAttributes[name.toLowerCase()] = normalizedName;
        }

            return $(selector).find("[" + attribute + "='true']").each(function (index, element) {
                addValidationExpando(element);
                element.dispose = function () { dispose(element); element.dispose = null; };
                if ($.inArray(element, validatorsArray) === -1) {

            }
        }
        function registerUpdatePanel() {
