Hi
Currently NServiceBus does not support this scenario. You might want to take a look at this recent thread Homegrown outbox (store and forward) for send-only endpoints and also the older one Outbox in an ASP.NET Core scenario.
The community-base solutions that you might find useful are
- GitHub - peto268/NServiceBus.WebOutbox
- GitHub - SzymonPobiega/NServiceBus.Connector.SqlServer: SQL Server connector for NServiceBus
