A continuación se muestra un extracto del archivo de configuración utilizado por el ejemplo anterior.

<?xml version="1.0" encoding="utf-8" ?>  
<configuration>  

  <configProtectedData>  

    <providers>  
      <clear />  
      <add  
         name="TripleDESProtectedConfigurationProvider"   
         type="Samples.Aspnet.TripleDESProtectedConfigurationProvider, protectedconfigurationproviderlib, Version=1.0.0.0, Culture=neutral,

    </providers>  

  </configProtectedData>  

</configuration>  

Comentarios

ASP.NET usa proveedores para realizar servicios específicos requeridos por una característica. Por ejemplo, la característica de pertenencia usa un proveedor para coordinar la persistencia de los datos de pertenencia en una base de datos.

En un archivo de configuración, los proveedores individuales se agregan a un providers elemento dentro de una sección de característica determinada.

La ProviderSettings clase representa un grupo determinado de valores que se agregan al providers elemento dentro de una sección de configuración. Normalmente, los atributos de configuración especificados por la add directiva incluyen un nombre, un tipo y otras propiedades.
