Unable to cast object of type 'System.String' to type
Did you recently upgrade the plugin? The problem is on the Dev environment or staging/production as well? Do you think .NET temp files are the issue (try deleting them)

Hi,
We using ImageResizer for its focal point feature. It has worked well for us but recently have this error pop up and breaking our site. Our underlying code has not changed, as far as we know so this is a mystery.
It seems to stem from this class:
[MediaDescriptor(ExtensionString = "png,gif,jpg")]
public partial class ImageFile : BaseImageData, IMedia, IFocalPointData
{
[BackingType(typeof(PropertyFocalPoint))]
public virtual FocalPoint FocalPoint { get; set; }
[ScaffoldColumn(false)]
public virtual int? OriginalWidth { get; set; }
[ScaffoldColumn(false)]
public virtual int? OriginalHeight { get; set; }
}
