Microsoft Visual Studio 2010 uses a new feature called the Extension Manager to add, remove, enable, and disable Visual Studio extensions. The Extension manager has a UI similar to that of the Windows Control Panel, and can be opened from the Tools menu in Visual Studio by selecting Extension Manager….
In addition, third party templates may now be installed from the New Project Dialog Box by clicking Search Online Templates… in the Templates pane.
To Enable Online Extensions download and usage, follow the below steps:
- From Visual Studio 2010 go to Options
- Extension Manager
- Check “Load per used extensions when running as administrator”
P.S. if you don’t have this option installed Visual Studio will notify you when selecting “Online Templates” from New Project dialog.
