I want to write a PC/SC application using VC++ 2010 in win7 x32 environment.
My program fails to compile with some linking error like this:

error LNK2019: unresolved external symbol _SCardReleaseContext@4 referenced in function "void __cdecl pscs_app(void)" (?pscs_app@@YAXXZ)

I guess that I need to include winscard.lib into my project, but I can't find it anywhere on my system. So I think I need to install something like a SDK or developer pack, but I can't find any suitable information about it on the web, can anybody help me please?
