I have just had time to catch up on some news around Biztalk Server and implementation of Enterprise Service Bus. If you are really keen on getting up-to-speed with the latest release of Biztalk Server 2009, you can access a public Beta through Microsoft Connect Site.
What is new in BizTalk Server 2009? Well it supports Windows Server 2008, Visual Studio 2008 SP1, SQL Server 2008 and the .NET Framework 3.5 SP1, which is great for all of you who are building apps on the latest frameworks and servers! Additionally it also includes support for RFID Mobile scenarios, new connectivity support and adapters. For more detailed news, visit Biztalk Roadmap site.
Additionally a new CTP release of ESB Guidance is also available at CodePlex, but main ESB CodePlex site is also worth checking out!
