NLog VS Serilog

What is it you're trying to accomplish? Either this is a regular expression problem (not really dotnet related) or you should try using structured logging, with a provider and sink that support it so you don't have to use regular expressions.

NLog

Log4Net does not get that much attention any more. From my understanding it served as an alternative for Log4J, but today better and more modern solutions have been created. I migrated a codebase over to .NET Core a couple of years ago, and it seemed that Log4net had issues running on Linux because of kernel calls inside their codebase. If you look at the version history on NuGet, it had just 3 patch releases last year. As an alternative, I would suggest to check out NLog.

C# -> Built in Logger, Log4Net, Serilog, NLog, e.t.c.

I would like to use a proper logger like https://github.com/nlog/nlog

I'm going to look at psframework mentioned elsewhere, but i make use of .NET NLog https://nlog-project.org/. it's not terribly hard to wire up, and is pretty feature rich.

have a look at this https://github.com/nlog/nlog/wiki/Context you dont want to make your own logger 99% of them time

For a more structured log file*) layout, you could use something like NLog with a PS wrapper.

NLog is another option here, with the buffering wrapper around an email target.

To learn more about Serilog, you can visit the documentation on their GitHub project. To learn more about Seq, you can visit the documentation on their website.

These projects use dependency injection for connections and have no logging although they are ready to log to the console via SeriLog setup in Program.cs.

See here: https://github.com/serilog/serilog/wiki/Configuration-Basics e.g.

Captured in public static void OnActivated() and note Log is SeriLog.

"Serilog": { "Using": [ "Serilog.Sinks.File" ], "Enrich": [ "WithHttpRequestId", "WithExceptionDetails", "WithClientIp" ], "MinimumLevel": { "Default": "Information" }, "WriteTo": [ { "Name": "File", "Args": { "path": "../../../../../Logs/MyApp/MyApp-.log", "rollingInterval": "Day", "retainedFileCountLimit": "7", "outputTemplate": "[{Timestamp:yyyy-MM-dd HH:mm:ss.fff zzz} {CorrelationId} {Level:u3}] {Username} {Message:lj}{NewLine}{Exception} {Properties:lj}{NewLine}" } } ] } 👆 I got the enricher names from serilog's wiki. The idea was to log the HTTPRequestId, ClientIp, and automagically log the details of every exception thrown (without having to do _logger.LogError(...)). However I don't see those details in the logs. In Program.cs: ``` var logger = new LoggerConfiguration() .ReadFrom.Configuration(builder.Configuration) .Enrich.FromLogContext() .CreateLogger();

You could also write a custom destructuring policy, assuming it's a flurl-specific public exception type and you only need certain properties of it. You'd implement IDestructuringPolicy and then add it to the configuration:

Serilog for logging

I've cloned https://github.com/serilog/serilog and I'm not sure what's going on with the multitargetting in the tests? Does this (below) mean, if the dev's OS is windows, then target framework 462 or 471? What should I do on my laptop, which only has the net6 and fw48 sdk installed?
