Unresolved external symbols in beginners CUDA program

I create a new Win32 Console App as an empty project I am running Windows 7 64bit with Visual Studio 2008 C++. I am trying to get the sample code from the bottom of this article to build: http://www.ddj.com/architect/207200659

I add CUDA Build Rule v2.3.0 to the project's custom build rules. It is the only thing with a checkbox in the available rule files list

I create moveArrays.cu in the Source Files (folder/filter???)

In that file I add the following code:

// moveArrays.cu
//
// demonstrates CUDA interface to data allocation on device (GPU)
// and data movement between host (CPU) and device.

#include <stdio.h>
#include <assert.h>
#include <cuda.h>
int main(void)
{
   float *a_h, *b_h;     // pointers to host memory
   float *a_d, *b_d;     // pointers to device memory
   int N = 14;
   int i;
   // allocate arrays on host
   a_h = (float *)malloc(sizeof(float)*N);
   b_h = (float *)malloc(sizeof(float)*N);
   // allocate arrays on device
   cudaMalloc((void **) &a_d, sizeof(float)*N);
   cudaMalloc((void **) &b_d, sizeof(float)*N);
   // initialize host data
   for (i=0; i<N; i++) {
      a_h[i] = 10.f+i;
      b_h[i] = 0.f;
   }
   // send data from host to device: a_h to a_d 
   cudaMemcpy(a_d, a_h, sizeof(float)*N, cudaMemcpyHostToDevice);
   // copy data within device: a_d to b_d
   cudaMemcpy(b_d, a_d, sizeof(float)*N, cudaMemcpyDeviceToDevice);
   // retrieve data from device: b_d to b_h
   cudaMemcpy(b_h, b_d, sizeof(float)*N, cudaMemcpyDeviceToHost);
   // check result
   for (i=0; i<N; i++)
      assert(a_h[i] == b_h[i]);
   // cleanup
   free(a_h); free(b_h); 
   cudaFree(a_d); cudaFree(b_d);
}

When I build I get these errors:

1>------ Build started: Project: CUDASandbox, Configuration: Debug x64 ------
