I am trying something like this

var x = Newtonsoft.Json.JsonConvert.DeserializeObject<Dictionary<string, object>>(json_data);

      "DurationMilliseconds":227.2,
      "StartMilliseconds":0,
      "Children":[  
         {  
            "Id":"dbf36d18-8abd-43f1-ae9b-640cb3d77a87",

Using http://jsonclassgenerator.codeplex.com/ and manual tuning, I've reduced the needed classes to 2 (root and childs classes are actually the same):

Note that you can give any name to your classes, what makes the link with the JSON are the [JsonProperty("...")] attribute above each property.

using System;
using Newtonsoft.Json;

namespace WpfApplication3
{
    public partial class MainWindow
    {
        private readonly string json = @"
{  
   ""Id"":""1405de4d-2823-43b4-8dba-66c2714bc7f"",
   ""Name"":""Sports/Boxing"",
   ""Started"":""\/Date(1472064057630)\/"",
   ""DurationMilliseconds"":227.2,
   ""MachineName"":""RED"",
   ""CustomLinks"":null,

            ""Name"":""Red Eagle"",
            ""DurationMilliseconds"":212,

There are two ways:

1. You may Deserialize (using Newtonsoft.Json) to JObject:

   var jsonObj = JsonConvert.DeserializeObject(json) as JObject;
   
   // Then you may access properties like this: 
   var id = jsonObj ["Id"].Value<int>();
   

Also, there is a possibility to do traversing of this "tree" object. More details at http://www.newtonsoft.com/json/help/html/t_newtonsoft_json_linq_jobject.htm

2. You may generate classes out of JSON (e.g. http://json2csharp.com/) and write something like this:

   var rootObject = Newtonsoft.Json.JsonConvert.DeserializeObject<RootObjectType>(json);
