NServiceBus 8.1.4 – Patch release available

Hi everyone,

We’ve just released NServiceBus 8.1.4.

Fixed Bugs

  • #6890 The DataBus does not work with NewtonsoftJsonSerializer
  • #6887 Message serialization and deserialization fails when using SystemJsonSerializer and sending a large message using DataBusProperty

How to know if you are affected

You are affected if:

You are using the DataBus to send messages with large payloads and you are using one of these serializers:


  • When NServiceBus tries to deserialize the message’s DataBusProperty, a null reference exception is thrown.
  • When NServiceBus tries to serialize the message’s DataBusProperty, an exception is thrown:

    Unhandled exception. System.NotSupportedException: Serialization and deserialization of ‘System.Type’ instances are not supported. Path: $.LargePayload.Type.

When to upgrade

You should upgrade immediately if you’re affected, otherwise during your next maintenance window.

Where to get it

You can install NServiceBus 8.1.4 from NuGet.

With thanks,
The team in Particular
