Answer 1

Problem was in version of next packages:

You have to update it and problem will be solved.

Answer 2

I had the same problem and when I tried different checking I found out that there is a selector in my css file like this that cause the problem:

.glyphicons-icon _:-o-prefocus, .glyphicons-icon { background-image: url(../images/glyphicons.png); }

it seems that Microsoft.Ajax.Utilities.CssParser has a problem with _: css selector. I removed the line and it's working.

Answer 3

The same error can appear when one try to add javascript files to a StyleBundle.
