Set Filename for the Attachment

If we want to send message through a SMTP Port with attachments and we want to set the attachment's filename, we have to set MIME.FileName property.

When we are designing the orchestration, Intellisense don't show us this property:



We have to write "Message_1(MIME." and Intellisense will show us this property:



This is because MIME.FileName is a PartContextPropertyBase and Intellisense by default only show us the MessageContextPropertyBase properties.
