using custom system.text.json convertor in masstransit

Question

I am trying to use my custom Json convertor in Masstransit But could not find any ways to add my JsonConverterFactory class.
Besides, I could not find any information In the documentation about serialization based on system.text.json
do you have any idea?
Thanks

Answer 1

MassTransit currently (as of v7) does not use System.Text.Json, it uses Newtonsoft.Json. There are no plans underway to add support for it at this time.

If you were using JSON.net, you can add additional converters by configuring the JSON serializer.

cfg.ConfigureJsonSerializer(settings => settings.Converters.Add(...))

It's important to leave the existing converters or you may break existing functionality.

Answer 2

As of v8, System.Text.Json is the default Json serializer.

Configuring the serializer remains the same:

x.UsingRabbitMq((ctx, cfg) =>
{
    // ...

    cfg.ConfigureJsonSerializerOptions(opts =>
    {
        opts.Converters.Add(YOUR_CUSTOM_CONVERTER);
        return opts;
    });                
});
