Error with using Bitmap class in project

Question

Hi I am trying to divide the logic of my simple WPF program to projects in .NET. I created project with type Class Library. After i tried to use class Bitmap in class of project but validator find error
"The type or namespace name 'Bitmap' could not be found (are you missing a using directive or an assembly reference?) C:\Users\Микола\documents\visual studio 2013\Projects\dragNDrop\BusinessLogic\Util.cs" How to solve this trouble?

P.S. Sorry i'm only started to studing .NET, and their types of Projects

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Drawing;

namespace BusinessLogic
{
    class Util
    {
        public Bitmap cropImage(Bitmap img, Rectangle cropArea)
        {
            Bitmap bmpImage = new Bitmap(img);
            return bmpImage.Clone(cropArea, bmpImage.PixelFormat);
        }
    }
}

You need using System.Drawing;

Open the Solution Explorer. In your project folder, right-click 'References'. Click 'Add reference'. In the list, check System.Drawing. Now the assembly reference is added to your project. Combined to the using line that you already have, the compiler should not complain anymore.
