Error while compressing Expected semicolon or closing curly-brace, found '-'

Getting error when enable optimizations is true.

BundleTable.EnableOptimizations = true;

Work-around tried unsuccessfully as this also fails when BundleTable.EnableOptimizations = true;
Working as expected when BundleTable.EnableOptimizations = false; (in development mode)

Hello, Jitan!

This is a error at the Microsoft Ajax Minifier library level. Replace the BundleTransformer.MicrosoftAjax module by the BundleTransformer.NUglify module.

If this error still occurs, try to add in the Web.config file the following setting:

<configuration>
  …
  <bundleTransformer …>
    …
    <nuglify>
      <css ignoreErrorList="CSS1062" />
      …
    </nuglify>
    …
  </bundleTransformer>
  …
</configuration>

Thank you for replying @Taritsyn,

I am currently testing the first suggestion.
Sure will add the second one also.

Will update once done
