Ich benötige spezifische JSON-Einstellungen pro Controller in meinem ASP.NET MVC 6-WebApi. Ich habe dieses Beispiel gefunden, das für MVC 5 funktioniert (hoffe ich!):Force CamelCase unter ASP.NET WebAPI Pro Controller

using System;
using System.Linq;
using System.Web.Http.Controllers;
using System.Net.Http.Formatting;
using Newtonsoft.Json.Serialization;

public class CamelCaseControllerConfigAttribute : Attribute, IControllerConfiguration 
{
    public void Initialize(HttpControllerSettings controllerSettings, HttpControllerDescriptor controllerDescriptor)
    {
        var formatter = controllerSettings.Formatters.OfType<JsonMediaTypeFormatter>().Single();
        controllerSettings.Formatters.Remove(formatter);

        formatter = new JsonMediaTypeFormatter
        {
            SerializerSettings = {ContractResolver = new CamelCasePropertyNamesContractResolver()}
        };

        controllerSettings.Formatters.Add(formatter);

    }
}
