Type initialization exception

I created imageHolder class:

public class ImageHolder : Image<Bgr, Byte>
   {
       private String imagePath;

       public ImageHolder(String path):base(path)
       {
          this.imagePath = path;
       }
       public String imgPathProperty
       {
           get
           { return imagePath; }
           set
           { imagePath = value; }
       }
   }

I create instance of the class and initialize it,like this:

private ImageHolder originalImageHolder;
 originalImageHolder = new ImageHolder(openFileDialog.FileName);

In runtime i get this exception:

The type initializer for 'Emgu.CV.CvInvoke' threw an exception.

Any idea why i get this exception and how can i fix it?

Thank you in advance.
