Log4net не вставляет в базу данных?

У меня есть настройка log4net и настроена для вставки в таблицу sql server 2005. Моя таблица называется Log. Когда я вызываю метод log4net, он не вводит никаких данных в базу данных журнала в SQL-сервере. Я не получаю никаких ошибок из кода клиента С#. Нужно ли добавлять пользователя в таблицу журналов в sql? Сейчас я использую проверку подлинности Windows.

Вот мой код sql для базы данных журнала:

CREATE TABLE [dbo].[Log](
[Id] [int] IDENTITY(1,1) NOT NULL,
[Date] [datetime] NULL,
[Thread] [varchar](255) NULL,
[Level] [varchar](50) NULL,
[Logger] [varchar](255) NULL,
[Message] [varchar](4000) NULL,
[Exception] [varchar](2000) NULL
) ON [PRIMARY] 

Вот мой класс, который я использую для вызова log4net.

public class ErrorLog : ILog
{
    log4net.ILog _Log;

    /// <summary>
    /// Initializes a new instance of the <see cref="ErrorLog"/> class.
    /// </summary>
    /// <param name="log">The log.</param>
    public ErrorLog(log4net.ILog log) : this()
    {
        _Log = log;
    }

    /// <summary>
    /// Initializes a new instance of the <see cref="ErrorLog"/> class.
    /// </summary>
    public ErrorLog()
    {
        _Log = LogManager.GetLogger(MethodBase.GetCurrentMethod().DeclaringType);

        log4net.Config.XmlConfigurator.Configure(); 
    }

    /// <summary>
    /// Informationals the specified message.
    /// </summary>
    /// <param name="message">The message.</param>
    public void informational(string message)
    {
        _Log.Info(message);
    }

    /// <summary>
    /// Informationals the specified message.
    /// </summary>
    /// <param name="message">The message.</param>
    /// <param name="innerException">The innerException.</param>
    public void informational(string message, Exception innerException)
    {
        _Log.Info(message, innerException);
    }

    /// <summary>
    /// Debugs the specified message.
    /// </summary>
    /// <param name="message">The message.</param>
    public void debug(string message)
    {
        _Log.Debug(message);
    }

    /// <summary>
    /// Debugs the specified message.
    /// </summary>
    /// <param name="message">The message.</param>
    /// <param name="innerException">The innerException.</param>
    public void debug(string message, Exception innerException)
    {
        _Log.Debug(message, innerException);
    }

    /// <summary>
    /// Errors the specified message.
    /// </summary>
    /// <param name="message">The message.</param>
    public void error(string message)
    {
        _Log.Error(message);
    }

    /// <summary>
    /// Errors the specified message.
    /// </summary>
    /// <param name="message">The message.</param>
    /// <param name="innerException">The innerException.</param>
    public void error(string message, Exception innerException)
    {
        _Log.Error(message, innerException);
    }

    /// <summary>
    /// Warnings the specified message.
    /// </summary>
    /// <param name="message">The message.</param>
    public void warning(string message)
    {
        _Log.Warn(message);
    }

    /// <summary>
    /// Warnings the specified message.
    /// </summary>
    /// <param name="message">The message.</param>
    /// <param name="innerException">The innerException.</param>
    public void warning(string message, Exception innerException)
    {
        _Log.Warn(message, innerException);
    }
}

Вот мой интерфейс:

public interface ILog
{
    /// <summary>
    /// Informationals the specified message.
    /// </summary>
    /// <param name="message">The message.</param>
    void informational(string message);

    /// <summary>
    /// Informationals the specified message.
    /// </summary>
    /// <param name="message">The message.</param>
    /// <param name="innerException">The innerException.</param>
    void informational(string message, Exception innerException);

    /// <summary>
    /// Debugs the specified message.
    /// </summary>
    /// <param name="message">The message.</param>
    void debug(string message);

    /// <summary>
    /// Debugs the specified message.
    /// </summary>
    /// <param name="message">The message.</param>
    /// <param name="innerException">The innerException.</param>
    void debug(string message, Exception innerException);

    /// <summary>
    /// Errors the specified message.
    /// </summary>
    /// <param name="message">The message.</param>
    void error(string message);

    /// <summary>
    /// Errors the specified message.
    /// </summary>
    /// <param name="message">The message.</param>
    /// <param name="innerException">The innerException.</param>
    void error(string message, Exception innerException);

    /// <summary>
    /// Warnings the specified message.
    /// </summary>
    /// <param name="message">The message.</param>
    void warning(string message);

    /// <summary>
    /// Warnings the specified message.
    /// </summary>
    /// <param name="message">The message.</param>
    /// <param name="innerException">The innerException.</param>
    void warning(string message, Exception innerException);
}
