VS2008 to VS2010 migration. Entity Framework

EF project migrated from VS2008 to VS2010 does not have ability to use "Add Code Generation Item" : list of Installed Templates is empty.

EF project created in VS2010 has  the only item in the list of "Installed Templates": ADO.NET EntityObject Generator. It is places in "Code" sublist, not in "Code Generation" as I would expect.

Template SSDLToSQL10.tt that is used for EF model generation is located in
C:\Program Files\Microsoft Visual Studio 10.0\Common7\IDE\Extensions\Microsoft\Entity Framework Tools\DBGen\ folder
