MVC Bundle Not Working with Release Configuration (Debug is False)

08 Feb

I encountered problem with Scripts and Styles bundle when deploying ASP.Net MVC 4 application to Windows Azure. The site loaded without CSS and JavaScript and developer tools show bunch of URL bundles returning 404 errors.

Solution was to add the following code to web.config

<system.webServer>
  <modules runAllManagedModulesForAllRequests="true">
    <remove name="BundleModule" />
    <add name="BundleModule" type="System.Web.Optimization.BundleModule" />
  </modules>
</system.webServer>

When deploying with Release configuration manager, <compilation> debug is set to false and MVC minify all CSS and JavaScript files.

If run with debug="true" output is the following HTML.

<link href="/Content/themes/base/jquery.ui.core.css" rel="stylesheet"/>
<link href="/Content/themes/base/jquery.ui.resizable.css" rel="stylesheet"/>
<link href="/Content/themes/base/jquery.ui.selectable.css" rel="stylesheet"/>
<link href="/Content/themes/base/jquery.ui.accordion.css" rel="stylesheet"/>
<link href="/Content/themes/base/jquery.ui.autocomplete.css" rel="stylesheet"/>
<link href="/Content/themes/base/jquery.ui.button.css" rel="stylesheet"/>
<link href="/Content/themes/base/jquery.ui.dialog.css" rel="stylesheet"/>
<link href="/Content/themes/base/jquery.ui.slider.css" rel="stylesheet"/>
<link href="/Content/themes/base/jquery.ui.tabs.css" rel="stylesheet"/>
<link href="/Content/themes/base/jquery.ui.datepicker.css" rel="stylesheet"/>
<link href="/Content/themes/base/jquery.ui.progressbar.css" rel="stylesheet"/>
<link href="/Content/themes/base/jquery.ui.theme.css" rel="stylesheet"/>

But if run with debug="false", output is the following instead:

<link href="/Content/themes/base/css?v=LJDigUf9DCM1N7CIVASNPsU78xE9F_Int_B2M79n8CI1" rel="stylesheet"/>

    Inside RegisterBundles function in BundleConfig class just put:
    BundleTable.EnableOptimizations = false;
