If you’ve read my Setting up an MDM Server development environment post in the past, there is now a new white paper on the MDM Workbench developerWorks forum which I would definitely recommend taking a look at.
The White paper on using the MDM Workbench has updated information on setting up a development environment, with screen shots of the wizard used. It then takes you through subsequent tasks to create a working extension to the MDM Server, with essential information about working on the code in a team environment.
The information should provide a quick start for anyone new to the MDM Workbench. Please provide any feedback on the white paper in the forum thread.
