Hi,

I have a few workflows that I have built that use the extended email with list attachment or the extended email with custom sender. Recently I have been getting errors that show the following:

Could not deserialize object. The type 'Custom.Workflow.Activities.SendMailWListItemAttachments' could not be resolved.

I have un-installed and re-installed the .wsp and deployed globally. I have done iisresets and nothing seems to be resolving. Please advise
