To quote the blog entry from "Anthony @ MS" that Stu pointed out:
VS 2005 Extensions for .NET Framework 3.0 (WPF & WCF) CTP is Coming off the MS Download Center
In November 2006 Microsoft released a
CTP version of the VS 2005 Extensions
for .NET Framework 3.0 (WPF & WCF).
We released this CTP as a stop gap to
provide developers the needed (albeit
very limited) set tools to start
developing for the .NET Framework 3.0.
This was never intended to release as
a complete product and was only
intended as a stop gap until Visual
Studio 2008, codenamed Orcas was
released.
Since then Visual Studio 2008 has
released and SP1 is on the way. With
VS 2008 you have a set of tools
designed entirely to take advantages
of the functionality introduced with
WCF & WPF. Users who have been
developing using the CTP extensions
should have already migrated their
projects to VS 2008 to take advtange
of the new functionality which is far
better than what we were able to
deliver in the CTP.
On Monday, June 30th 2008, the license
for this CTP will expire. The
download will be removed from the MS
Download center. At that point any
existing users should work on
migrating their projects to VS 2008 to
take advantage of the fully supported
WPF & WCF support.

i guess it would have been nice of them to indicate up front that they had no intention of releasing a final form of the extensions.
