When you install TEE11 Beta in Eclipse you will notice their are two Team Explorer windows

  • Team Explorer 2010 – The old style window
  • Team Explorer – The new VS11 style window


This is an artefact of the beta as TEE transitions to the new VS UI.

I would recommend you use the new one as this will be the experience going forward. I certainly would not recommend having both open as I have shown in this screenshot
