ASP.NET Core: Problems loading dependencies of Javascript

The problem:

I've been trying to resolve some issues with my dependencies of Javascript such as jQuery and bootstrap for my project.

However, at this moment, none of these are working properly.

Diagnosis:

All started with jQuery not being loaded working locally and I detected that it was because of the order of these componentes: bootstrap was being called before jQuery inside the _Layout file.

For this, I made the following changes to my _Layout file:

<!DOCTYPE html>
<html>
<head>
    <meta content="text/html" charset="utf-8" http-equiv="content-type" />
    <meta name="viewport" content="width=device-width, initial-scale=1.0" />
    <title>@ViewData["Title"] - Plataforma Fantasy Park</title>

    <environment names="Development">
        <script src="//ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
        <script src="~/lib/bootstrap/dist/js/bootstrap.js"></script>
        <script src="~/js/jquery.dataTables.min.js" asp-append-version="true"></script>
        <script src="~/js/dataTables.bootstrap.min.js" asp-append-version="true"></script>
        <script src="~/js/site.js" asp-append-version="true"></script>

        <link rel="stylesheet" href="~/css/bootstrap-lumen.css" />
        <link rel="stylesheet" href="~/css/site.css" />
        <link rel="stylesheet" href="~/css/nestednavbar.css" />
        <link rel="stylesheet" href="~/css/dataTables.bootstrap.min.css" />
    </environment>

    <environment names="Staging,Production">
        <script src="https://ajax.aspnetcdn.com/ajax/jquery/jquery-3.2.1.min.js"
                asp-fallback-src="~js/jquery-3.2.1.js"
                asp-fallback-test="window.jQuery"
                crossorigin="anonymous"
                integrity="sha384-K+ctZQ+LL8q6tP7I94W+qzQsfRV2a+AfHIi9k8z8l9ggpc8X+Ytst4yBo/hH+8Fk">
        </script>
        <script src="https://ajax.aspnetcdn.com/ajax/bootstrap/3.3.7/bootstrap.min.js"
                asp-fallback-src="~/lib/bootstrap/dist/js/bootstrap.min.js"
                asp-fallback-test="window.jQuery && window.jQuery.fn && window.jQuery.fn.modal"
                crossorigin="anonymous"
                integrity="sha384-Tc5IQib027qvyjSMfHjOMaLkfuWVxZxUPnCJA7l2mCWNIpG9mGCD8wGNIcPD7Txa">
        </script>
        <script src="~/js/site.min.js" asp-append-version="true"></script>

        <link rel="stylesheet" href="https://ajax.aspnetcdn.com/ajax/bootstrap/3.3.7/css/bootstrap.min.css"
              asp-fallback-href="/css/bootstrap-sand.min.css"
              asp-fallback-test-class="sr-only" asp-fallback-test-property="position" asp-fallback-test-value="absolute" />
        <link rel="stylesheet" href="~/css/site.min.css" asp-append-version="true" />
    </environment>





    @RenderSection("css", required: false)
</head>
<body>

    <div class="container body-content">
        @RenderBody()
        <hr />
        <footer>
            <p>&copy; 2017 - Plataforma Fantasy Park</p>
        </footer>
    </div>




    @RenderSection("Scripts", required: false)
</body>
</html>

With this the error of 404: resource not found was over. However now the components are not working: Navbars, modals, and such.

This is an example of a View:

@model IEnumerable<Application.Models.Store>
@using Application.Models
@{
    ViewData["Title"] = "Index";
}
@Html.Partial("_NavBar")

@section scripts{

<script src="~/js/store-index.js" asp-append-version="true"></script>
<script type="text/javascript" src="~/js/jquery-3.2.1.js">

    var global = this;
    var wasclicked = 0;

    $(document).ready(function () {

        document.getElementById("modalbutton").onclick = function () {
            global.wasclicked = 1;
        };

        $('#modal-action-store').on('hidden.bs.modal', function () {
            global.wasclicked = 0;
        });

        $('#modal-action-store').on('shown.bs.modal', function () {
            if (global.wasclicked == 1) {
                var items = "<option value='0'>-- Seleccione Distrito --
</option>";
                $('#DistrictID').html(items);
            }
            $('#DepartmentID').change(function () {
                var url = '@Url.Content("~/")' + "Stores/GetDistrict";
                var ddlsource = "#DepartmentID";
                $.getJSON(url, { DepartmentID: $(ddlsource).val() }, 
function (data) {
                    var items = '';
                    $("#DistrictID").empty();
                    $.each(data, function (i, district) {
                        items += "<option value='" + district.value + "'>" + district.text + "</option>";
                    });
                    $('#DistrictID').html(items);
                });
            });
        });
    });
</script>

}

    <a id="createEditStoreModal" data-toggle="modal" asp-action="Create" data-target="#modal-action-store"

                    @Html.DisplayFor(modelItem => item.StoreArea)
                </td>
                <td>

                            data-target="#modal-action-store" asp-route-id="@item.StoreID" class="btn btn-info">Edit</a>
                    </div>

                </td>
            </tr>}
    </tbody>
</table>

@Html.Partial("_Modal", new BootstrapModel
{
    ID = "modal-action-store",
    AreaLabeledId = "modal-action-store-label",
    Size = ModalSize.Medium
})

Update:

In this View, if I take out this reference src="~/js/jquery-3.2.1.js" and leave it like this:

@section scripts{

<script src="~/js/store-index.js" asp-append-version="true"></script>
<script type="text/javascript">

I get the error on the line for store-index.js:

Failed to load resource: the server responded with a status of 404 (Not Found).

This is the code for the Navbar called:

<script src="~/lib/bootstrap/dist/js/bootstrap.js"></script>

<nav class="navbar navbar-inverse navbar-inverse navbar-fixed-top">
<div class="container-fluid">
    <div class="navbar-header">
        <button type="button" class="navbar-toggle" data-toggle="collapse" data-target=".navbar-collapse">
            <span class="sr-only">Menu</span>
            <span class="icon-bar"></span>
            <span class="icon-bar"></span>
            <span class="icon-bar"></span>
        </button>
        <a asp-area="" asp-controller="Home" asp-action="Index" class="navbar-brand">Plataforma Fantasy Park</a>
    </div>
    {...}
</div>
</nav>

I'm hoping to find some help and what might be wrong for these components to stop working. What else can I check besides the _Layout?

Update:

Continuing with the validations this is the result of the Network Tab:

  1. There is a reference to jquery twice, once in your '_layout' and once in your view. Only one in the layout should be required.
  2. I cannot see a boostrap.css or boostrap.min.css file. You have one for datatables, one for 'lumen', but not the primary bootstrap css file (i.e. https://getbootstrap.com/dist/css/bootstrap.min.css).
  3. Looks like you have two bootstrap.js references too (once in layout and once near your navbar - again, only one should be required).
