No muestra items en "Agregar nuevo elemento" Visual 2005

[Tucky5]

A mí me pasó eso hace un mes. Busqué por internet y la solución que me daban no me funcionó (perdona, pero no recuerdo ahora mismo). Así que tuve que reinstalar el Visual Studio.
He encontrado esto, prueba a ver si a tí te funciona.

How to: Restore Default Project Templates

If you accidentally delete the default project templates that are included with Visual Studio, you can use this procedure to restore them without reinstalling Visual Studio.

To restore the default project templates
In the command prompt, navigate to the location of devenv.exe. This file is located in <Visual Studio Installation Path>\Common7\IDE.

Type "devenv /installvstemplates" and press Enter.

Note:
If you are using an Express Edition of Visual Studio, type "<ExpressName>Express /installvstemplates" where <ExpressName> is either VB, VJS, or VCS for Visual Basic, Visual J#, and Visual C#, respectively.


If this procedure does not restore the default templates, reinstall Visual Studio.


Suerte!!!
