Hi Artyom,
Thanks for the reply.

Actually, I have built it as a static library , in order to stay consistent
with the mac version.
After successful compilation, I got 2 .lib files
libsoci_core-vc80-d-2_2.lib
libsoci_postgresql-vc80-d-2_2.lib
I added those 2 library files in my VS2005 project, along with all the
necessary include files
#include "include/soci.h"
#include "include/soci-config.h"
#include "include/soci-postgresql.h"
It compiles just fine.
The runtime did require that I copy several Postgresql DLL (libpq.dll,
ssleay32.dll, etc) in the current directory.
After that, the final executable launched successfully...
But it couldn't find the backend ("failed to find shared library" message).

Just to be on the safe side, I tried your suggestion, by copying both static
library files .lib in the current directory.
No luck : whether they're present or not doesn't change the error message.
I'm really puzzled, as the error message I saw is a strong indication that
libsoci_core.lib is correctly included in my project IMHO.
I don't know why the core would be included correctly, and the backend is not.
I had another idea : is there a particular #define to change, to signal
VC2005 that I want the output be recognized as a static library? Maybe
the executable is expecting DLL output, hence the message?
(and before you ask, I did build SOCI with the project branch
soci\build\msvc80\lib\ ;-)
Any suggestion is most welcome.
Have a nice day
Andrew
