Team Explorer Builds doesn't show build definitions, says "Item with the same key has already been added"

I recently migrated from Visual Studio 2010 to 2012 (version: 11.0.51106.01 Update 1). In Team Explorer -> Builds, I've added some build definitions for my favorites. Now when I open Team Explorer -> Builds, I don't see any build definitions, and instead I see an error:
An item with the same key has already been added.

Why is this happening?
How can I solve this problem?
I suppose I could somehow remove these favorite assembly definitions, but where are they stored?

This appears to be a known issue with TFS2012.

Cause. ... If there are multiple built queues in a favorite assembly definition (for example, a gated and private assembly), VS2012 will create an empty favorite assembly and then throw this error when it reloads the favorites.

Correction: No AFAIK yet.



Workaround: Edit %LOCALAPPDATA%\Microsoft\Team Foundation\4.0\FavoritesStore\<GUID>.xml

:

  • Workaround: remove the line <FavoriteItem Name="" ...

    . However VS2012 will create it again.
  • Permanent workaround: Remove relevant assembly definitions from favorites.

Some ( a blog post , connection error , Connection Error 2 ) propose to remove the TFS cache, but it did not work.
