CSS bundling in ASP.NET does not include minified version in production

Question

I have an MVC 5 application.

I have this code in _Layout.cshtml

<head>
   ......
   @Styles.Render("~/Content/estilos")

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

I have this other code in the view:

@section styles
{
    @Styles.Render("~/Content/dataTables")
}

On the other hand, I have this in BundleConfig.cs file:

bundles.Add(new StyleBundle("~/Content/estilos").Include(
                      "~/Content/style.css",
                      "~/Content/site.css"));
bundles.Add(new StyleBundle("~/Content/dataTables").Include(
                      "~/Content/DataTables/css/dataTables.bootstrap4.css",
                      "~/Content/DataTables/css/fixedColumns.bootstrap4.css"));

With respect to files, these are present:

~/Content/site,css
~/Content/style.css
~/Content/DataTables/css/dataTables.bootstrap4.css
~/Content/DataTables/css/dataTables.bootstrap4.min.css
~/Content/DataTables/css/fixedColumns.bootstrap4.css
~/Content/DataTables/css/fixedColumns.bootstrap4.min.css

When I deployed the site, and set "debug = false" in "compilation debug="false" targetFramework="4.7.2" setting in web.config, I realized that only "estilos" bundle is loaded. "dataTables" bundle is missing.

When I set "debug = true", all CSS files are loaded.

What may be happening here?

Finally.. the problem was because the name of the bundle was the same as the physical path the dataTable css were in. — jstuardo, Nov 07 '18 at 19:23

You should avoid using existing directory paths as bundle name (directory names are case-insensitive as in Windows environment). Just rename with other name that not exist as physical directory path and the bundling should work:

bundles.Add(new StyleBundle("~/Content/tables").Include(
                      "~/Content/DataTables/css/dataTables.bootstrap4.css",
                      "~/Content/DataTables/css/fixedColumns.bootstrap4.css"));

Razor View

@section styles
{
    @Styles.Render("~/Content/tables")
}
