Can I use Xpress free version of Coderush in commercial work or this version is recommended for learning solutions?
I'm afraid I don't quite understand what you mean by "commercial work". Am I right in my assumption that you mean using CodeRush Xpress while working on a commercial project? If so, yes, you can certainly use it. If you mean something else, please describe this in greater detail. Anyway, you'll get a better answer by contacting management@devexpress.com.
