Very recently there is a new version of BizTalk Deployment Framework available through codeplex. It used to be hosted by Scott Colestock. It is 4th release of the framework. I will use it in my High Performance Learning for BizTalk environment (see post part I, post part II, post IIa, post part III, post part IVa). I will continue with this environment any time soon, discussing development, then deploying, administration/monitoring through SCOM and some troubleshooting stuff.
