pyd == dll, or how to create a c-extension with visual studio

[Axel Kowald]

Hi,

if I want to create a c-extension for python with visual studio under 
windows, do I compile my source code into a dll and then simply rename 
the extension to pyd ??  Or is a pyd file different from a dll ?
If someone has a simple Visual-Studio project file for creating a python 
c-extension, I would be grateful for a copy.

Many thanks,

              Axel Kowald
