Comentarios

ASP.NET supervisión del estado permite al personal de producción y operaciones administrar aplicaciones web implementadas. El System.Web.Management espacio de nombres contiene los tipos de eventos de mantenimiento responsables de empaquetar los datos de estado de la aplicación y los tipos de proveedor responsables de procesar estos datos. También contiene tipos auxiliares que ayudan durante la administración de eventos de mantenimiento.

WebErrorEvent proporciona información sobre los errores causados por problemas con la configuración o el código de la aplicación. Un ejemplo es el error emitido por ASP.NET cuando se encuentra un error en una página.
