I create Console Application in VC++ 2010, and add the following code to it:

#include <d3d10.h>
#include <d3dx10.h>
#include <DxErr.h>

#pragma comment(lib, "d3d10.lib")
#pragma comment(lib, "d3dx10.lib")
#pragma comment(lib, "dxgi.lib")
#pragma comment(lib, "dxerr.lib")

int _tmain(int argc, _TCHAR* argv[])
IDXGIFactory* pDXGIFactory;
CreateDXGIFactory(IID_IDXGIFactory, ( void** )&pDXGIFactory);

return 0;

Building this project, I have linker error: error LNK2001: unresolved external symbol _IID_IDXGIFactory

Now I create Console Application with MFC support, and add the same code. The build is successful. What is wrong in the first case? Why MFC project is built successfully, and non-MFC project fails?

Of course, Win32 project is better, Console application is just reproducible sample, My actual problem is in Dll project.
Solved by adding dxguid.lib to the linker list.
