NServiceBus 6.4.1, 6.3.7, 6.2.7 - Patch releases available

Hi everyone,

We’ve just released NServiceBus 6.4.1, 6.3.7, and 6.2.7.

Fixed bugs

  • #4993 HandleCurrentMessageLater causes message loss when using Outbox

How to know if you are affected

You are affected if you are using the IMessageHandlerContext.HandleCurrentMessageLater API on endpoints with the Outbox feature enabled.


Messages which should be reprocessed by using IMessageHandlerContext.HandleCurrentMessageLater will instead be discarded by the Outbox since the message id is already flagged as successfully processed.

Should you upgrade immediately

You should upgrade immediately if you are using IMessageHandlerContext.HandleCurrentMessageLater. Note that due to the nature of HandleCurrentMessageLater, using this API in conjuction with the Outbox is not supported. The patch will detect the invalid configuration and throw an exception to prevent message loss.
