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>
To fix "Object reference not set to an instance of an object," you should try running Microsoft Visual Studio as an administrator. You can also try resetting the user data associated with your account or updating Microsoft Visual Studio to the latest version.
Render generates multiple script tags for each item in the bundle EnableOptimizations is set to false. When optimizations are enabled, Render generates a single script tag to a version-stamped URL which represents the entire bundle.
I misused ViewBag
in master layout file to consume in other pages. My structure made ViewBag
as a required field so I had to instantiate it before. But I forgot to instantiate it which caused to fire such this error and it seems to be irrelevant to Scripts.Render
.
