Exceptions not being logged

[awjrowe]

I see there has been a previous bug registered about exceptions not getting passed to log4net so they can be output using the conversion pattern but it is marked as closed. I've run into the same problem and just tried your sample programs with the the controller modified as

    [HttpGet]
    public IEnumerable<WeatherForecast> Get()
    {
        var rng = new Random();
        WeatherForecast[] weatherForecast = Enumerable.Range(1, 5).Select(index => new WeatherForecast
        {
            Date = DateTime.Now.AddDays(index),
            TemperatureC = rng.Next(-20, 55),
            Summary = Summaries[rng.Next(Summaries.Length)]
        })
        .ToArray();

        _logger.LogTrace("Weather forecast ready!");
        _logger.LogError("Weather forecast broken!", new ApplicationException("Exception thrown"));

        return weatherForecast;
    }

and the Exception is not getting logged even though it is in your conversion patterns

		<conversionPattern value="%date %5level %logger.%method [%line] - MESSAGE: %message%newline %exception" />

can you confirm this behaviour please.

II think the problem with the code above is the order of arguments provided to LogError. LogError(message, ex) tries to format the exception into the string, the correct one is LogError(ex, message).
