NServiceBus.Callbacks 2.0.2 and 1.1.3 - Patch releases available

(Tim Bussmann) #1

Hi everyone,

We’ve just released NServiceBus.Callbacks 2.0.2 and 1.1.3.

Fixed bugs

How to know if you are affected

You are affected if your callback continuation blocks or delays the executing thread. Examples of this would include, but are not limited to, issuing callback requests inside of while and for loops.


This bug can lead to various side effects like:

  • messages that are not fully consumed from the pipeline
  • transport transactions timing out
  • endpoints no longer processing messages
  • endpoints processing messages with a lower level of concurrency
  • message handler invocation getting delayed

Should you upgrade immediately

Although this bug only manifests under certain circumstances, the exact conditions and impact can vary. Therefore, we recommend all users of NServiceBus.Callbacks to update to the latest version immediately.

With thanks,

The team in Particular
