Difficulty setting up environment

Hello,

I have had the hardest time getting my computer setup to build WCF
applications.

I am running Windows 2003 64bit edition and I have Visual Studio 2005. I
ran through the first WCF Virtual Lab and am trying to duplicate the lab on
my computer and it doesn't seem to work.

I have downloaded and installed the Windows Vista SDK but that didn't seem
to give me the stuff I needed; or at least not all of it.

I have tried installing the WinFX RuntimeComponents 3.0 Beta 2 and then I
uninstalled and installed .NET Framwork 3.0 to no avail.

In the virtual lab, all/most of the WCF DLLs were in the 2.0 Framwork
folder. Is this still possible? Ideally I would like to use the 2.0
framework with the WCF components which I am read is essentially the 3.0
framework plus other features. Am I just getting hung-up on terminology?

I would greatly appreciate your help.

Thanks,

Marshall
