Enterprise Library and Exceptions

Jeice

I'm trying to use Enterprise Library to handle all my exceptions, and I've followed the tutorials on the internet, but I keep getting the same error. So, after 2 days of googling and looking for ways to fix the error, I come to you guys for ideas/solutions.

This is the code I'm trying to run:

using System;
using System.Data;
using System.Configuration;
using System.Collections;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;
using Microsoft.Practices.EnterpriseLibrary.Logging;
using Microsoft.Practices.EnterpriseLibrary.ExceptionHandling.Logging;
using Microsoft.Practices.EnterpriseLibrary.ExceptionHandling;
using System.Collections.Specialized;
using Microsoft.Practices.EnterpriseLibrary.ExceptionHandling.Configuration;

decimal num = 9;
decimal den = 0;

try
{
decimal result = num / den;
}

catch (DivideByZeroException exception)
{
bool rethrow = ExceptionPolicy.HandleException(exception, "Exception Policy"); // this is where the error is happening
if (rethrow)
{
throw;
}
}

This is the xml that I generated using Enterprise Library Configuration and following the tutorials:

This is the error message I keep getting:

Invalid section name. The section 'exceptionHandlingConfiguration' does not exist in the requested configuration file 'C:\...\web.config' or the file 'C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Config\machine.config'. Make sure that the 'enterpriseLibrary.configurationSections' configuration section exists in one of the files and that the section 'exceptionHandlingConfiguration' is defined.

I am using C# in Microsoft Visual Studio to run this.

I am no expert on C# or this library.
However, the section name in your configuration file is "enterpriselibrary.configurationSettings" and the one that the error message indicates should exist is "enterpriseLibrary.configurationSections".
