I just try to upgrade the component from 4.5 to 5.0.

I found that i gave error on this line of code
tmpDateString = exifData.Item(Aurigma.GraphicsMill.Codecs.ExifDictionary.DateTimeOriginal)

The error as below:
Run-time exception thrown : System.ArgumentException - The value with the specified key does not exist in collection.
Parameter name: key


The code was working fine under 4.5

Please advice.

Hello,

The file you sent doesn't contain such EXIF tag. You should add additional check before using this value using Contains(...) method.
