Firstly saying it doesn't work doesn't help anyone to help you. To become a good programmer you need to be good at phrasing questions as well as knowing answers.
What happens exactly? what are you doing? Which version are you referring to? Which code fragment are you trying to compile? Obviously bearing in mind this article talks about the new version of C++ .NET so you need to be specific about which .NET version you are running. Is it a beta? The new release? The old version 2002? These may not be relevant to your particular question but never leave anything out when asking for help. The more detail you can give the more accurate the answers are likely to me. Hope this helps.
