I have a .Net Worker Service app which has multiple threads. I want to log each thread into separate file to make it easier to read the logs. Any ideas to implement this?

Personally, id just sink to a proper log aggregator like SEQ or anything else. Structure your logs the way you want, and never worry about files again unless its backupTheGeneral– TheGeneral2021-08-30 22:50:38 +00:00Commented Aug 30, 2021 at 22:50

A common way of deciding which sink to write to at run-time is to use the Serilog.Sinks.Map:
Log.Logger = new LoggerConfiguration()
.WriteTo.Map(_ => Thread.CurrentThread.ManagedThreadId,
(threadId, wt) => wt.File($"log-{threadId}.log"))
.CreateLogger();
Log.Information("Hello from the main thread");
var task1 = Task.Run(() => Log.Information("Hello from thread X"));
var task2 = Task.Run(() => Log.Information("Hello from thread Y"));
Task.WaitAll(task1, task2);
Log.CloseAndFlush();
You should consider limiting the number of open sinks when using this approach.
