Both Developer and Administrator Training Kits have been recently released. Inside of these training kit you can expect functional Virtual Machines, with the BizTalk software installed, training module documents and PowerPoint presentations. This is the content that you would typically find in a Microsoft Official Curriculum course. The best part about these kits is they are made available for free.
I had the opportunity to collaborate with Jerry Anderson from Pluralsight on the Administration course. My contributions primarily focused on Module 6: Monitoring a BizTalk Environment with System Center Operations Manager (SCOM).
