We have just announced that previously available from and supported only by the open source .NET community Codeplex ESB Guidance is going to be included into the Microsoft BizTalk Server 2009 Suite with a new name "Microsoft BizTalk ESB Toolkit 2.0". You can still download it for free from the Codeplex starting as soon as mid-June, but the customer support and continues release of new versions will now be managed by Microsoft BizTalk Server product team.

You can also watch here my interview I was given to the TechEd 2009 Online on the subject of leveraging BizTalk Server 2009 as an Enterprise Service Bus. Just follow this link: http://www.msteched.com/online/view.aspx?tid=5f1e71d5-4902-40d5-9a94-d4dd5085698a
