Fix To: Bundles Are Not Working After Hosting To MVC Application

In this article we are going to see how we can fix if you are getting some reference errors, or if your bundles are not getting configured properly in your server. I have fixed this issue, and here I am going to share you how you can also fix this error. I hope you will like this.

Background

Recently I hosted one of my MVC application to Microsoft Azure cloud. And we usually publish our application in release mode right? So here the problem comes. You can replicate the same issue in your local machine itself. Just make the debug attribute to false in your Web.config as follows.

[xml]
<compilation debug="false" targetFramework="4.5" />
[/xml]

And when you run, you will get a prompt as follows.

Just select Run without debugging option. Now once after your application is run, you can see some script errors in your browser console saying that the references are not loaded correctly.

And finally I could find the solution. Here we will see that.

Bundles Are Not Working After Hosting To MVC Application

As I said, the problem is with your bundle config settings. There are few things you must check before going to the last fix.

Please make sure that you have used StyleBundle for creating the style bundle

Please make sure that you have used ScriptBundle for creating the style bundle

Make sure that you are loading the styles using @Styles.Render

Make sure that you are loading the scripts using @Scripts.Render

Make sure that the folder structure is same as you have in local system

If none of the above solution works, you can try the last one.

Make sure that virtual path of bundles doesn’t contains the folder names you have in your solution

I will explain it. In my case my bundles were as follows.

[html]
@Styles.Render("~/Scripts/JQWidgets/CSS")
@Scripts.Render("~/Scripts/JQWidgets")
[/html]

And I have the folders JQWidgets in my root script folder. This was making the issue.

Now what I did is, I just changed my bundle config settings in BundleConfig.cs as follows(Renaming the folder)

[csharp]
bundles.Add(new ScriptBundle("~/Scripts/Grid")
bundles.Add(new StyleBundle("~/Scripts/Grid/Styles")
[/csharp]

And I referenced the same bundles as follows in my views.

[csharp]
@Styles.Render("~/Scripts/Grid/Styles")
@Scripts.Render("~/Scripts/Grid")
[/csharp]

Please try these steps and build your application. Once that is done you can publish your application to cloud. I hope this will solve your issue. Have a happy coding.
