Hello,
I wish to take a call in this question. Express editions are for non commericial learning purpose. WF and WCF are available in Professional edition that is provided to you for free via Dreamspark or BizSpark. So kindly get hold of it rather than trying to get a patch. One more important information that i would like to share here is VS 2008 & VS 2005 can work parallely i.e. they both can run on a System.
If you are student, please contact your college for MSDN AA{ Academic Alliance } through which you can get all these required editions for free.
Thanks.
