Enable bundling and minification in debug mode in ASP.NET MVC 4

I can't believe I cannot find other questions about this, but: how does one enable bundling in debug mode? I know how it is enabled for release mode, but in debug mode I cannot find a way to enable the bundling.

Is this even possible or am I missing something?

Solution 1:

You can enable this by adding

BundleTable.EnableOptimizations = true;

in your RegisterBundles method (BundleConfig class in the App_Start folder).

check http://www.asp.net/mvc/tutorials/mvc-4/bundling-and-minification for more info

You could also change your web.config:

<system.web>
    <compilation debug="false" />
</system.web>

But this would disable debug mode entirely so I would recommend the first option.

Finally, to get the best of both worlds, use the #if compiler directive like this:

#if DEBUG
            BundleTable.EnableOptimizations = false;
#else
            BundleTable.EnableOptimizations = true;
#endif

Solution 2:

add BundleTable.EnableOptimizations = true; in Application_Start() method of Global.asax file
