This section is all about configuration, from memory configuration to INI, JSON and XML.

• Configuration

  This is the 'hello world' of configuration. Just use WebApplication.Configuration read/write values to/from it.

• Configuration - Options

  Use IOptions at the most basic.

• Configuration - Environment variables

  Load environment variables and display all of them.

• Configuration - INI file

  Read from INI file.

• Configuration - INI file - Options

  Read from INI file (with nested keys) and IOptions.

• Configuration - XML file

  Read from XML file.

  Note: This Xml Configuration provider does not support repeated element.

  The following configuration settings will break:

  <appSettings>
    <add key="webpages:Version" value="3.0.0.0" />
    <add key="webpages:Enabled" value="false" />
  </appSettings>
  

  On the other hand you can get unlimited nested elements and also attributes.
