+Json.NET is a popular high-performance JSON framework for .NET
+
+## Serialize JSON
+
+```csharp
+Product product = new Product();
+product.Name = "Apple";
+product.Expiry = new DateTime(2008, 12, 28);
+product.Sizes = new string[] { "Small" };
+
+string json = JsonConvert.SerializeObject(product);
+// {
+//   "Name": "Apple",
+//   "Expiry": "2008-12-28T00:00:00",
+//   "Sizes": [
+//     "Small"
+//   ]
+// }
+```
+
+## Deserialize JSON
+
+```csharp
+string json = @"{
+  'Name': 'Bad Boys',
+  'ReleaseDate': '1995-4-7T00:00:00',
+  'Genres': [
+    'Action',
+    'Comedy'
+  ]
+}";
+
+Movie m = JsonConvert.DeserializeObject<Movie>(json);
+
+string name = m.Name;
+// Bad Boys
+```
+
+## LINQ to JSON
+
+```csharp
+JArray array = new JArray();
+array.Add("Manual text");
+array.Add(new DateTime(2000, 5, 23));
+
+JObject o = new JObject();
+o["MyArray"] = array;
+
+string json = o.ToString();
+// {
+//   "MyArray": [
+//     "Manual text",
+//     "2000-05-23T00:00:00"
+//   ]
+// }
+```
