Configuración ELMAH: la sección de configuración de error no reconocido

Question

Configuración:

• Windows XP
• .NET Framework 3.5 SP1
• ASP .NET MVC Versión 1

He estado tratando de establecer hasta ELMAH siguiendo las instrucciones en http://code.google.com/p/elmah/wiki/MVC pero acabo de recibir el siguiente error cuando presione F5:

 
Description: An error occurred during the processing of a configuration file required to service this request. Please review the specific error details below and modify your configuration file appropriately. 

Parser Error Message: Unrecognized configuration section elmah/errorlog. 

Source Error: 


Line 30: 
Line 31:  <elmah> 
Line 32:   <errorlog type="Elmah.XmlFilerErrorLog, Elmah" logPath="~/App_Data" /> 
Line 33:  </elmah> 
Line 34: 

Y, aquí está el fichero de configuración:

Resuelto

El siguiente bloque debería haber ido tras </system.webServer> y antes </configuration>

<elmah> 
     <errorLog type="Elmah.XmlFileErrorLog, Elmah" logPath="~/App_Data" /> 
    </elmah> 

Answer 1

XML es sensible a mayúsculas:

<section name="errorLog" type="Elmah.ErrorLogSectionHandler, Elmah"/> 

vs

<elmah> 
    <errorlog type="Elmah.XmlFilerErrorLog, Elmah" logPath="~/App_Data" /> 
</elmah> 

Cambie el nombre del elemento de registro de errores de registro de errores y lo hará (debería) de trabajo.
