Running an ASP.NET MVC 4 app in release mode does not bundle and minifiy the js files

Question

When I run my ASP.NET MVC 4 app in release mode, the bundles are still outputting the unminified and separate js files, instead of bundling and minifying it into fe

Answer 1

My bundle was too big. I had to break it down into smaller parts and it worked fine. Maybe some variable conflicted after minification.

Put this line at end of your bundleconfig only for test...

BundleTable.EnableOptimizations = true;

If you open the minified file, you will see something like this.

    /* Minification failed. Returning unminified contents.
    (5079,1-2): run-time warning JS1195: Expected expression: .
    (5080,18-19): run-time warning JS1004: Expected ';': :
    (5084,18-19): run-time warning JS1004: Expected ';': :
    (5091,18-19): run-time warning JS1004: Expected ';': :
    (5095,20-21): run-time warning JS1197: Too many errors. The file might not be a JavaScript file: ;
.....

Breaking down you bundle, you can isolate the issue.

Hope this may help someone.
