或者:
据我所知，MS从未发布过针对VS2005的最终WCF插件，但最终的CTP仍然存在:

Alternatively:
From what I can tell MS never released a final WCF add in for VS2005, but the final CTP is still out there: http://downloads.zdnet.co.uk/0,1000000375,39328336s,00.htm

您可以使用该WCF插件，而不用15秒文章中提到的更通用，更beta的orcas扩展名.我相信CTP会为您提供添加服务参考"选项.

You can use that WCF add in instead of the more general and more beta orcas extension that is mentioned in the 15 seconds article. I believe the CTP will give you the "add service reference" option.
