Serilog - C# - configuration

Question

Hello, As suggested by @Karen Payne MVP

https://betterstack.com/community/guides/logging/how-to-start-logging-with-serilog/

The global part of the project is probably already done by the library. I can call this via Log in every class. It looks good so far. Does not appear and color console does not work either. Maybe I need more

Install-Package Serilog
Install-Package Serilog.Sinks.Console
Install-Package Serilog.Sinks.File
Install-Package Serilog.Sinks.map

It is not viewable if I have never needed it. Maybe I need more.

My goal.

I am using a WinForm application and would like to open a console window with debugging in parallel. (For Debug, not for Release) // add console as logging target .WriteTo.Console() I use a WinForm application and want parallel a console open debugging.

Log File --- C:\Temp\Log\2023-06-07-MachineA.log If the file bigger than 25MByte use the next file.Log File I would like to write a new file from a certain size.

Inside file.

 Like this[{Timestamp:yyyy-MM-dd HH:mm:ss.fff} [{Level}] {Message}{NewLine}{Exception}
   But not work too. maybe mistake with [ ]  only open?

Why does ColoredConsole no longer work?

Can you please help me. Thank you in advance.

Answer 1

See the following project, and read the readme.md file

Answer 2

The colored console only works for console and ASP.NET Core projects, not Windows Forms.
