When using this setup, the extra exception properties are not output

private static readonly ILogger Logger = new LoggerConfiguration()            .Enrich.WithExceptionDetails()            .WriteTo.Console()            .CreateLogger();

Hi@eloisetaylor5693 , thanks for reaching out to us.

Serilog.Sinks.Console sink's default output template does not display enriched properties at all. Not forSerilog.Exceptions and not for any other sink (like standardEnrich.FromLogContext() orEnrich.WithProperty).

You need to specify custom template includingProperties like that:

.WriteTo.Console(outputTemplate: "{Timestamp:yyyy-MM-dd HH:mm:ss.fff zzz} [{Level:u3}] {Message:lj}{NewLine}{Exception} {Properties:j}")

Then your output will look like that:

2018-12-17 07:30:13.045 +01:00 [ERR] An error occurredSystem.Exception: An exception message.   at SerilogExceptionsLibUsingConsoleLogger.Program.ThrowAnException() in C:\Users\kraj…

Strange, could you prove a very small reproduction?

Simple example:

using Serilog;using Serilog.Exceptions;using System;namespace SerilogExceptionsLibUsingConsoleLogger{    public static class Program    {        private static readonly ILogger Logger = new LoggerConfiguration()            .Enrich.WithExceptionDetails()            .WriteTo.Console()            .CreateLogger();        public static void Main()        {            try            {                ThrowAnException();            }            catch (Exception ex)            {                Logger.Error(ex, "An error occurred");            }            finally            {                Console.ReadLine();            }        }        private static void ThrowAnException()        {            var exception = new Exception("An exception message.");            exception.Data.Add("someData", "This is some exception data");            throw exception;        }    }}

With packages:

<?xml version="1.0" encoding="utf-8"?><packages>  <package version="2.7.1" targetFramework="net461" />  <package version="4.1.0" targetFramework="net461" />  <package version="3.1.1" targetFramework="net461" /></packages>

Gives this output:

[15:10:10 ERR] An error occurredSystem.Exception: An exception message.   at SerilogExceptionsLibUsingConsoleLogger.Program.ThrowAnException() in C:\Code\SerilogExceptionsLibUsingConsoleLogger\SerilogExceptionsLibUsingConsoleLogger\Program.cs:line 35   at SerilogExceptionsLibUsingConsoleLogger.Program.Main() in C:\Code\SerilogExceptionsLibUsingConsoleLogger\SerilogExceptionsLibUsingConsoleLogger\Program.cs:line 18

But I would have expected to see more exception detail than exception.ToString() gives. For example I would expect to see the data properties in the logged error, based on the documentation for this library.

What's more, many other sinks are the same. On the other hand, I think that you got a point, that we could be explicit about it in the docs. I will add some guidance regarding the topic.

Hope that helps.

I have extended theREADME.md with short description and an example in84b62d1.
That should help, thanks again@eloisetaylor5693 .
