The AppFabric Customer Advisory Team (CAT) (formerly known as BizTalk Rangers) opened a new blog. Their focus is not just on BizTalk Server but now also on Windows Server AppFabric, WCF, WF, AppFabric Caching and StreamInsight (CEP), etc.
Besides the mentioned blog there is also a CAT site. This contains information on other CATs as well. For a full description of the teams and all the relevant url’s see Richard’s post.
Very interesting stuff written by great experts; worth reading!
