<p>Is there a good reference, or summary list, of new features in WCF 2.0/VS2010?</p>

<p>I'm trying to do a justification proposal for a project, to migrate from Jabber to WCF.</p>

Not answering your question in particular, but WCF 2.0's not going to come out for quite some time, so I'd base my evaluation against the current WCF version.
