In my first post I mentioned that there was a TFS IP for Microsoft internal people. Later it was released on CodePlex at http://orchestrator.codeplex.com/. Please read the documentation at here and list of new features in 1.4. Currently there are following activities in the latest 1.5 version:
I will write a few posts later to explain how to use the new activities. Note that there is no activity for Visual Studio Lab Management (VSLM), and I do not plan to add it. This is because VSLM client SDK or API is not publically available and will not be supported (suppose you get it via reflection) in 2010 release. The recommended approach for automating this part is to use the lab workflow activities (Windows workflow), i.e. create a workflow in Visual Studio IDE in XAML and invoke it. One can read Customizing Lab Management Workflow to get more details on this.
Please let me know if you have any feedback on TFS IP, any bug to fix, or any new feature you want to have. I will evaluate and add appropriate ones as soon as I am free. Thanks!
