Method not found: 'Void MailKit.MailTransport.Send(MimeKit.MimeMessage, System.Threading.CancellationToken, MailKit.ITransferProgress)'. why?

Yes. I have exact same issue. I'm very surprised that the author @lukencode has not responded at all since April. I guess it's time not to use this nugget packages

For me, this issue happens when I have MailKit version 3.0.0 or greater installed.

It looks like MailKit 3.0.0 changed the signature to return a string instead of a void. Link to commit
