Support for .NET 5

andreasohlund · May 31, 2021, 6:51am

Hi everyone,

We now support running NServiceBus on .NET 5. We confirm that all runtime features that NServiceBus depends on have been tested — both on Linux and Windows.

Note that there are some restrictions when using NServiceBus with .NET 5:

A custom databus serializer must be used in ASP.NET apps. The BinaryFormatter used by the default serializer is prohibited in .NET 5 for ASP.NET apps.
If a saga property is a record type, that record type must be mutable so it can be deserialized.

We have also released version NServiceBus 7.4.7, which fixes an issue with single file deployment in .NET 5.

Where to get it

You can install the new version of NServiceBus from NuGet.

With thanks,
The team in Particular

Please read our release policy for more details.

I am having a issue where Dictionary<string,object> is not deserialized properly. This only seems to happen when them message is of type Event

         "FieldAnswers": {
    "Id": {
      "$type": "System.Text.Json.JsonElement, System.Text.Json",
      "ValueKind": 3
    },
    "MerchantId": {
      "$type": "System.Text.Json.JsonElement, System.Text.Json",
      "ValueKind": 3
    },

What serializer is this? (GitHub - NServiceBusExtensions/NServiceBus.Json: Add support for NServiceBus message serialization via System.Text.Json ?)

I am not using that serializer? Should I use it?

I am doing the following:

endpointConfiguration.UseSerialization<NewtonsoftSerializer>();

Tried that still not working… maybe i am doing something wrong.

It is weird because it works when i use Send… it is not working when using Publish
