I am creating an integration with my App using the .NET SDK. My App is written in VB.NET, and I have installed the package “DocuSign.eSign.dll” V 8.3.0 (latest).

I have downloaded the C# JWTConsole example and tried that - everything works great! - I get the emails, I can sign, I see the envelope in the dashboard, status is “sent” etc… all good. This example is also using the DocuSign.eSign.dll package.

My main project is in VB.NET, so I convert (using the Telerik C# to VB converter) the C# code, and paste that in to my project… with a little bit of tweaking here and there I can get it all “working” - insomuch as I can run it, I get no errors, I can log in to the Docusign dashboard where I can see the envelope with a status of “sent”, I even get webhooks from DocuSign with status of “envelope_sent” and “client_sent” - but I get no Signer email - I have checked that the email address is correct. I can click RESEND on the dashboard, but I still get no email.

What could I be doing wrong? - as far as I can tell, both the C# example code and the VB code are close to identical and when I step through the code checking variable / parameter values, they all look identical.

I can share an example envelope ID with you privately if this would help you diagnose the issue.

Any help would be gratefully received!
