OpenCV downloaded from NuGet giving Unresolved Externals LNK2019 - c++

Question

I downloaded OpenCV from NuGet on MSVS 2017, and ran a code I had found on this very site:
#include "stdafx.h"
#include <opencv2/highgui/highgui.hpp>
#include <opencv2/core/core.hpp>
#include <opencv2/imgproc/imgproc.hpp>
using namespace std;
using namespace cv;
int main()
{
Mat image = imread("C:\\Users\\Chubak\\Pictures\\index.jpg");
if (image.empty())
return -1;
imshow("TEST", image);
waitKey();
return 0;
}
But when I run the code I get this extremely unintelligible errors that I don't understand:

I understand that unresolved externals error is related to missing obj files but don't they come with the NuGet Package?
I also found this question but all the links given in the answers are no longer working, so this may or may not be a duplicate.
