Self-tracking entities template missing

When i create an entity data model and select Add Code Generation Item i don't see any ADO.NET Self-Tracking Entity Generator(i only see ADO.NET EntityObject Generator). What may be the problem? I am using visual studio 2010 ultimate. I installed and then uninstalled ado.net entity framew开发者_如何转开发ork ctp 3.

This generator is normally included with Visual Studio 2010 (whereas the POCO one is found in the online gallery). Try running devenv.exe /InstallVSTemplates to reinstall the templates.
