Exception Detail and Health Monitoring in ASP.NET 2.0

I really liked the original exception management block put out by Microsoft.  The reason is because it included all the information relating to an exception - not just the Message property.  It made production debugging a breeze.  Now with ASP.NET 2.0 and Health Monitoring something similar has been created but it doesn't quite cover all the details.  I first ran into this in an application where I had created a custom exception, ArgumentFormatException, and passed along two additional properties.  After puttering through the underpinnings of the Health Monitoring feature I noticed that the exception information is captured using the Message property of the Exception by the EventLogWebProvider class.  In order to beef up the data returned by my exception I put in a Message property which overrides the base version:

public override string Message
{
    get
    {
        StringBuilder message = new StringBuilder(base.Message);
        if (!string.IsNullOrEmpty(ExpectedFormat))
        {
            message.Append(Environment.NewLine);
            message.AppendFormat(CultureInfo.CurrentCulture, StringResources.ParameterExpectedFormat, ExpectedFormat);
        }
        if (!string.IsNullOrEmpty(ActualValue))
        {
            message.Append(Environment.NewLine);
            message.AppendFormat(CultureInfo.CurrentCulture, StringResources.ParameterActualValue, ActualValue);
        }
        return message.ToString();
    }
}

After re-running the tests voila I now have more detailed exceptions:

• Exception information:
• Exception type: ArgumentFormatException
• Exception message: The variable does not match the expected format.
• Parameter name: emailAddress
• Expected Format: ^([a-zA-Z0-9_\-\.']+)@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.)|(([a-zA-Z0-9\-]+\.)+))([a-zA-Z]{2,4}|[0-9]{1,3})(\]?)$
• Actual Value: xxxx
