ASP.NET Web API: use camel casing for your JSON objects

There is a general agreement to use PascalCasing for your objects in .NET, this in contrast to JavaScript where camelCasing is the default.  This is a little bit unfortunate when you are using ASP.NET Web API and want to return a JSON object to your JavaScript object. By default the properties will be PascalCased because of the fact that your C# objects are PascalCased as well.

Luckily this is an easy one to fix using the Json.NET serializer. Inside the WebAPIConfig class, add the following lines:

	public static class WebApiConfig
	{
	public static void Register(HttpConfiguration config)
	{
	// Web API configuration and services
	// Web API routes
	config.MapHttpAttributeRoutes();
	//config.Routes.MapHttpRoute(
	// name: "DefaultApi",
	// routeTemplate: "api/{controller}/{id}",
	// defaults: new { id = RouteParameter.Optional }
	//);
	var jsonFormatter = config.Formatters.OfType<JsonMediaTypeFormatter>().First();
	jsonFormatter.SerializerSettings.ContractResolver = new CamelCasePropertyNamesContractResolver();
	}
	}
