Adding Bundles to existing ASP.NET Webforms solution

I am trying to add Bundles to an existing ASP.NET Webforms solution but my bundles always render empty and I am unsure why. I have been following this blog post.

So far I have:

  • Added the Microsoft ASP.NET Web Optimization Framework NuGet package
  • Ensured required references are included
  • Tried using debug="false" and debug="true" in Web.config
  • Added the following code to my solution

Global.asax.cs

protected void Application_Start(object sender, EventArgs e)
{
    BundleConfig.RegisterBundles(BundleTable.Bundles);
}

App_Start/BundleConfig.cs

public class BundleConfig
{
    // For more information on Bundling, visit http://go.microsoft.com/fwlink/?LinkID=303951
    public static void RegisterBundles(BundleCollection bundles)
    {
        bundles.Add(new ScriptBundle("~/bundles/Global").Include(
            "~/js/jquery-{version}.js",
            "~/js/jquery-ui.js"));

        bundles.Add(new ScriptBundle("~/bundles/GlobalHead").Include(
            "~/js/modernizr*"));

        bundles.Add(new StyleBundle("~/Content/Global").Include(
            "~/css/site.css"));
    }
}

Site.Master

<head runat="server">
    <asp:PlaceHolder runat="server">
        <%: Scripts.Render("~/bundle/GlobalHead") %>
        <%: Styles.Render("~/Content/Global") %>
    </asp:PlaceHolder>
</head>
<body>
    <%: Scripts.Render("~/bundle/Global") %>
</body>

Web.Config

<namespaces>
    <add namespace="System.Web.Optimization" />
</namespaces>

Update

To be clear, when I open a web page and inspect the resources with chrome dev tools, I can see

Content/Site.css
bundle/Global.js
bundle/GlobalHead.js

But when inspecting them they have no content.

Simple solution, I had some typing errors.

In the Site.Master I missed the 's' from the end of bundles. Making my Site.Master look like this.

<head runat="server">
    <asp:PlaceHolder runat="server">
        <%: Scripts.Render("~/bundles/GlobalHead") %>
        <%: Styles.Render("~/Content/Global") %>
    </asp:PlaceHolder>
</head>
<body>
    <%: Scripts.Render("~/bundles/Global") %>
</body>
