Cannot find System.Drawing.dll in reference (1 answer)

Closed 6 years ago.

I am developing on Windows Phone 7.1 and can not find System.Drawing, for example in this code

public static System.Drawing.Bitmap sfondo_panorama 
{
    get 
    {
        object obj = ResourceManager.GetObject("sfondo_panorama", resourceCulture);
        return ((System.Drawing.Bitmap)(obj));
    }
}

I don't think System.Drawing available in WP7 and I'm not really sure what you are trying to do but try System.Windows.Media and System.Windows.Media.Imaging.
