Before code fix applied

public static void Main(string[] args)
{
    _logger.Trace(
        string.Format(
            ""Important message. Parameters: [ID1={0}]"",
            1234567),
        new Exception());
}

After code fix applied

public static void Main(string[] args)
{
    string traceLogMessage = string.Format(
            ""Important message. Parameters: [ID1={0}]"",
            1234567);
    _logger.Trace(
        new Exception(), traceLogMessage);
}
