+<?xml version="1.0" encoding="utf-8"?>
+<root>
+  <!-- 
+    Microsoft ResX Schema 
+    
+    Version 2.0
+    
+    The primary goals of this format is to allow a simple XML format 
+    that is mostly human readable. The generation and parsing of the 
+    various data types are done through the TypeConverter classes 
+    associated with the data types.
+    
+    Example:
+    
+    ... ado.net/XML headers & schema ...
+    <resheader name="resmimetype">text/microsoft-resx</resheader>
+    <resheader name="version">2.0</resheader>
+    <resheader name="reader">System.Resources.ResXResourceReader, System.Windows.Forms, ...</resheader>
+    <resheader name="writer">System.Resources.ResXResourceWriter, System.Windows.Forms, ...</resheader>
+    <data name="Name1"><value>this is my long string</value><comment>this is a comment</comment></data>
+    <data name="Color1" type="System.Drawing.Color, System.Drawing">Blue</data>
+    <data name="Bitmap1" mimetype="application/x-microsoft.net.object.binary.base64">
+        <value>[base64 mime encoded serialized .NET Framework object]</value>
+    </data>
+    <data name="Icon1" type="System.Drawing.Icon, System.Drawing" mimetype="application/x-microsoft.net.object.bytearray.base64">
+        <value>[base64 mime encoded string representing a byte array form of the .NET Framework object]</value>
+        <comment>This is a comment</comment>
+    </data>
+                
+    There are any number of "resheader" rows that contain simple 
+    name/value pairs.
+    
+    Each data row contains a name, and value. The row also contains a 
+    type or mimetype. Type corresponds to a .NET class that support 
+    text/value conversion through the TypeConverter architecture. 
+    Classes that don't support this are serialized and stored with the 
+    mimetype set.
+    
+    The mimetype is used for serialized objects, and tells the 
+    ResXResourceReader how to depersist the object. This is currently not 
+    extensible. For a given mimetype the value must be set accordingly:
+    
+    Note - application/x-microsoft.net.object.binary.base64 is the format 
+    that the ResXResourceWriter will generate, however the reader can 
+    read any of the formats listed below.
+    
+    mimetype: application/x-microsoft.net.object.binary.base64
+    value   : The object must be serialized with 
+            : System.Serialization.Formatters.Binary.BinaryFormatter
+            : and then encoded with base64 encoding.
+    
+    mimetype: application/x-microsoft.net.object.soap.base64
+    value   : The object must be serialized with 
+            : System.Runtime.Serialization.Formatters.Soap.SoapFormatter
+            : and then encoded with base64 encoding.
+
+    mimetype: application/x-microsoft.net.object.bytearray.base64
+    value   : The object must be serialized into a byte array 
+            : using a System.ComponentModel.TypeConverter
+            : and then encoded with base64 encoding.

+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"
+//   ]
+// }
