Create a Team Project Programatically

You can create the team projects programmatically, but you need to duplicate all the work that Project Creation Wizard (and all the project creation plugins) does. Unfortunately, there is no publicly exposed API to do all of that. Since this is very laborious, there are two options for you:

1. Automate the Project Creation Wizard UI. Very cheap, but not very extensible.
2. Examine what the Project Creation Wizard does, and make wrappers for all the calls it does and invoke them your self. This is error prone, but will be much more resilient to failures than option 1.

Your best option is UI automation..
