I started my new project in ASP.NET Core and I have a question.
I have 2 loggers: a) nLog, that have it's config in nlog.config file b) serilog, that have it's config in appsettings.json
At this moment, I have 2 locations to store logs: fileName="${basedir}/logs/EPR/nlog-all-${shortdate}.log - nLog "SerilogFile": "logs/serilog-{Date}.txt" - serilog
My question is, how to get basedir catalog in appsettings.json file.
One option is to set an environment variable with the base path at startup:
Environment.SetEnvironmentVariable("BASEDIR", AppDomain.CurrentDomain.BaseDirectory);
Then use "%BASEDIR%/logs/serilog-{Date}.txt" in the config.
Short: You can't in appsettings.json.
Longer: You can in code via the static PlatformServices class.
PlatformServices.Default.Application.ApplicationBasePath;
and then use replace or whatever you seem fit to replace the ${basedir} with the value returned by ApplicationBasePath, then pass it to your loggers configuration.
Sidenote: You shouldn't use PlatformServices outside of the Startup/Programm class, since they are static and bad to test etc.
