+// Version information for an assembly consists of the following four values:

+//      Major Version
+//      Minor Version

+// In order to sign your assembly you must specify a key to use. Refer to the

+//
+// Use the attributes below to control which key is used for signing. 
+//
+// Notes: 
+//   (*) If no key is specified, the assembly is not signed.
+//   (*) KeyName refers to a key that has been installed in the Crypto Service
+//       Provider (CSP) on your machine. KeyFile refers to a file which contains
+//       a key.
+//   (*) If the KeyFile and the KeyName values are both specified, the 
+//       following processing occurs:
+//       (1) If the KeyName can be found in the CSP, that key is used.
+//       (2) If the KeyName does not exist and the KeyFile does exist, the key 
+//           in the KeyFile is installed into the CSP and used.
+//   (*) In order to create a KeyFile, you can use the sn.exe (Strong Name) utility.
+//       When specifying the KeyFile, the location of the KeyFile should be
+//       relative to the project output directory which is
+//       %Project Directory%\obj\<configuration>. For example, if your KeyFile is
+//       located in the project directory, you would specify the AssemblyKeyFile 
+//       attribute as [assembly: AssemblyKeyFile("..\\..\\mykey.snk")]
+//   (*) Delay Signing is an advanced option - see the Microsoft .NET Framework
+//       documentation for more information on this.

DebuggingWindow.resx

+<?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.Runtime.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.
