JSON.NET

The default serializer that comes preinstalled with Cambion is called JsonNet and uses Newtonsoft.Json to serialize the data for the transport. This does not require any specific configuration, and is used if no other serializer is specified. Should you want be verbose about it you can still manually define that it should be used

public void ConfigureServices(IServiceCollection services)
{
    services.AddCambion()
        .UseJsonNetSerializer();
}
