@pvkekem As far as I know, this project is no longer maintained. Even in the README.md file there is a notification:

Notice: This project is no longer maintained.

If I were you, I would start using an official successor of the Microsoft Ajax Minifier - NUglify

OK - will check it out.
I'm using it combined with RequestReduce - any chance there is a successor of that as well?

I doubt it, because the RequestReduce has not been updated for a very long time.

@pvkekem Since you seem to have made a successful change/PR with the current code, I'd like to ask a question, if you don't mind. I cloned master, opened the solution, and tried to build, but got build errors in the JSUnitTest project. For example Error 29 The type or namespace name 'JSError' could not be found (are you missing a using directive or an assembly reference?) D:\dev\AjaxMin\JSUnitTest\Common\TestHelper.cs 679 41 JSUnitTest. Is there something special you did to get a clean build?
