c# - write-to not working from AppSettings with Serilog 2.1 -

i used serilog 1.x , following worked there:

in code:

log.logger = new loggerconfiguration().readfrom.appsettings().createlogger();

in app.config:

<add key="serilog:write-to:rollingfile.pathformat" value="c:\temp\myservice\log-{date}.log" />

but serilog 2.1 seems write-to isn't working app.config. when put them straight code works want them app.config. wrong code/app.config?

i luckily resolved myself. seems in 2.x version there need serilog:using every sink in app.config. added following use rollingfile , seq:

<add key="serilog:using:rollingfile" value="serilog.sinks.rollingfile" /> <add key="serilog:using:seq" value="serilog.sinks.seq" />

and both rolling files , seq works.
