How can I return camelCase JSON serialized by JSON.NET from ASP.NET MVC controller methods?

by

My problem is that I wish to return camelCased (as opposed to the standard PascalCase) JSON data via ActionResults from ASP.NET MVC controller methods, serialized by JSON.NET.

As an example consider the following C# class:

public class Person
{
    public string FirstName { get; set; }
    public string LastName { get; set; }
}

By default, when returning an instance of this class from an MVC controller as JSON, it’ll be serialized in the following fashion:

{
  "FirstName": "Joe",
  "LastName": "Public"
}

I would like it to be serialized (by JSON.NET) as:

{
  "firstName": "Joe",
  "lastName": "Public"
}

How do I do this?
