Bundling CSS and Scripts in Web Forms application

Question

I am here on a pickle about bundling my CSS and Scripts to my Web Forms application.

First of all, I'd like to point out that I was following this tutorial: http://blogs.msdn.com/b/rickandy/archive/2012/08/14/adding-bundling-and-minification-to-web-forms.aspx

I have already in the App_Start the class BundleConfig that looks like this:

using System.Web;
using System.Web.Optimization;

namespace SitePessoal.Web
{
    public class BundleConfig
    {
        public static void RegisterBundles(BundleCollection bundles)
        {
            bundles.Add(new ScriptBundle("~/bundles/jquery").Include(
                        "~/Scripts/jquery/core/jquery-{version}.js"));

            bundles.Add(new ScriptBundle("~/bundles/jqueryui").Include(
                        "~/Scripts/jquery/core/jquery-ui-{version}.js"));

            bundles.Add(new StyleBundle("~/CSS/css").Include(
                        "~/CSS/Estilos.css", 
                        "~/CSS/Print.css", 
                        "~/CSS/Styles.css"));
        }
    }
}

Also, I have downloaded the Optimization package with Nugget, so afterwards I went to my Global.asax file and tried to register this in the Application_Start method like this:

void Application_Start(object sender, EventArgs e) 
{
    // Code that runs on application startup  
    BundleConfig.RegisterBundles(BundleTable.Bundles);
    BundleTable.EnableOptimizations = true;
}

Unfortunately, this is where things do not work. Unfortunately, it keeps underlining the class with red and giving me the following messages:

Error   3   The name 'BundleTable' does not exist in the current context
Error   4   The name 'BundleTable' does not exist in the current context
Error   2   The name 'BundleConfig' does not exist in the current context

Any ideas as to why this may be happening? Thanks in advance!

Best regards,
Mad

I solved the problem @MadGatsu encountered following the same tutorial.

@Pricey is correct, and %MadGatsu correctly adds references to the Global.asax, including,

<%@ Import Namespace="System.Web.Optimization" %>
<script RunAt="server">        
    void Application_Start(object sender, EventArgs e)
    {
          BundleConfig.RegisterBundles(BundleTable.Bundles);

But there is a little more to it.

I deduce, based on the lack of Global.asax.cs, that we have Websites. In this case, we need to put our Bundleconfig.cs file in the special aspnet folder, App_Code. Do not add a App_Start folder to contain the file because it will not work. Simply moving my BundleConfig.cs to App_Code from App_Start corrected the 'BundleConfig' does not exist in the current context error.

Indeed your solution fixed the issue with the error message I was getting about "BundleConfig" not existing in the current context! Marked as solution. Thank you! :)

You probably fixed this already but just in case it's of use to anyone.. you probably need to add a reference to System.Web.Optimization and your BundleConfig class namespace SitePessoal.Web to your Global.asax.cs

Example:

using System.Web.Optimization;
using SitePessoal.Web;

namespace SitePessoal.Web.Application
{
    public class Global : HttpApplication
    {
        private void Application_Start(object sender, EventArgs e)
        {
              BundleConfig.RegisterBundles(BundleTable.Bundles);
              BundleTable.EnableOptimizations = true;
        }
    }
}

You probably also need to add the System.Web.Optimization namespace to your pages in your web.config if you haven't done it already, because it is not enough just to add the reference to the Microsoft.AspNet.Web.Optimization package via NuGet.

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

Hi Pricey, thanks for giving a possible answer. In fact, this topic was still open because I did not solve it at all yet. I will try your solution and give feedback as soon as possible (aka tomorrow!). Many thanks regardless of the result.

Hi Pricey, I haven't got time to test this out until now. Very busy at work. I tried your solution, but it still does not work. I have a Web Site, not Web application, so I do not have a Globa.asax.cs class file. Instead, I added to the Global.asax this: <%@ Import Namespace="System.Web.Optimization" %> <%@ Import Namespace="SitePessoal.Web" %> But it shows me error that BundleConfig does not exist in this context. In web.config file everything is fine and the System.Optimization is already there. Any more ideas? Thanks @Pricey.
