MVC5 Object reference not set to an instance of an

Question

I'm using Asp.net MVC5 and haven't encountered such this ambiguous error since 4 years working with Microsoft MVC platform! The error occurs in Manage page in default MVC5 template. here in line 26 at the _layout.cshtml file:

Line 24:     <![endif]-->
Line 25: 
Line 26:     @Scripts.Render("~/js/intf")
Line 27:     <script>
Line 28:         if (document.documentMode === 10) {

The Stack Trace says:

Edit: As you wanted the bundling code, I placed one of them here:

bundles.Add(new ScriptBundle("~/js/intf").Include(//first internal scripts
                "~/js/jquery*",
                "~/js/modernizr.js",
                "~/js/ie-prototype-polyfill.js",
                "~/js/prettyPhoto.js"));

NOTE: If I commentize the error lines (style/script bundling lines) The error will be @ViewBag.Title as the new error! I think the Razor view Engine got into trouble here, since it can't instantiate the view's codes requirements, But Why??

I know that some errors in working with Microsoft technologies aren't really related to the error that it says. Please left me your beneficial experiences. Thanks.

Update: The terse contents for ~/views/Account/Manage.cshtml file maybe useful:

@using Social.Models;
@using Microsoft.AspNet.Identity;

@{
    ViewBag.Title = "manage";
}

<div class="layout-app">

    <div class="row row-app margin-none">

        <div class="col-md-12">

            @if (ViewBag.HasLocalPassword)
            {
                 @Html.Partial("_ChangePasswordPartial")
            }
            else
            {
                 @Html.Partial("_SetPasswordPartial")
            }
        </div>
    </div>
</div>

Answer 1

Since I've used the ViewBag in master layout file as a required variable to show the project pages, missing its initialization caused to show me such this error! It was one of the irrelevant errors which I've seen from Microsoft development technologies so far.

Answer 2

Try to create a new javascript file in, for example, the folder Scripts in your MVC solution and call the file app.js (or anything else).

Then place the following line underneath the other @scripts.Render lines to run it.

<script src="@Scripts.Url("~/Scripts/app.js")"></script>

Otherwise add the file to a bundle.
