Disable Newtonsoft changing JSON case

I have a document which has a field:

{
   FOB: "..."
}

However when I return it:

    [HttpGet("{documentRef}")]
    public ActionResult<Ten> Get(string documentRef)
    {
        var data = _service.FindOneTen(documentRef);
        if (data != null) return data;
        Response.StatusCode = 400;
        return NotFound();
    }

It is converted to this: 

{
    fob: "..."
}

How can I stop this happening / Why is this happening?

I've seen examples of people using

PropertyNamingPolicy = null;

To disable it for MVC / the normal JSON which I tried and didn't work.

Startup:

    public void ConfigureServices(IServiceCollection services)
    {
        services.AddControllers().AddNewtonsoftJson();
    }

Edit

While Objects exposed on JSON web-api - how to stop the property names changing case? is solving the problem in one way, I would rather not need to specify for every field in the model.

use this

services.AddControllers().AddNewtonsoftJson(options=>
{
    options.SerializerSettings.ContractResolver = new DefaultContractResolver() {  };
});

If you're using .net core. You can try use default .net core serializer, it should preserve the original casing.

System.Text.Json.JsonSerializer.Serialize()

And also, you need to config in Startup.ConfigureServices()

services.AddMvc().AddJsonOptions(o => o.JsonSerializerOptions.PropertyNamingPolicy = null);

If you need to use Json.net then use this

services.AddMvc().AddNewtonsoftJson(o =>
{
o.SerializerSettings.ContractResolver = new DefaultContractResolver();
});
