NServiceBus 8.1.6 and 8.0.8 – Critical patch releases available

Hi everyone,

We’ve just released NServiceBus 8.1.6 and 8.0.8.

Fixed bugs

  • #6909 Combining the outbox with a message-driven transport may lead to message loss when publishing to multiple subscribers

How to know if you are affected

You are affected if one of these conditions apply:


  • When publishing an event to multiple subscribers only one of the subscribers receives the event. The subscriber that gets the event gets multiple copies of the same event.
  • When either the routing or the dispatch stage is extended, modifications to the headers will be applied to all related outgoing operations instead.

When to upgrade

You should upgrade immediately if you are using MSMQ or Azure Storage Queues transports or if you are extending the NServiceBus pipeline with behaviors in the IRoutingContext and IDispatchContext.

Where to get it

You can install the new versions of NServiceBus from NuGet.

With thanks,
The team in Particular
