Hello!

My serializer settings are ignored in production:

```
.UseSerializerSettings(new JsonSerializerSettings { TypeNameHandling = TypeNameHandling.All }

```

In dev environment everything works fine. Any ideas why?

The issue was fixed by using `GlobalConfiguration.Configuration.UseSerializerSettings` instead of `services.AddHangfire(cfg => cfg...)`
