Test Lab Guide: Demonstrating a File-based Extensible Connectivity 2.0 Management Agent (http://msdn.microsoft.com/en-us/library/hh859477(WS.10).aspx) is now available and is the first Test Lab Guide (TLG) to my knowledge published on the Microsoft Developer Network (MSDN) web site.
This TLG takes you through the creation of two management agents; one for Active Directory and a new ECMA 2.0 management agent. It then synchronizes objects between the two management agents and concludes with the ECMA 2.0 management agent doing an export of the new objects to an XML file. It also demonstrates a delta import on the ECMA 2.0 management agent.
Here is the TLG stack.
Enjoy (responsibly, of course)!
