Caution
Classes within the System.Drawing namespace are not supported for use within a Windows or ASP.NET service. Attempting to use these classes from within one of these application types may produce unexpected problems, such as diminished service performance and run-time exceptions. For a supported alternative, see Windows Imaging Components.
With that said, do you also echo Microsoft's warning, or do you have good news for me that the core of Spire.BarCode does not use System.Drawing, and you have lots of customers/users that are successfully using the component in high volume back end services.
Thanks!
