NLog configured with async while Serilog isn't

[saithis]

The current code wraps the NLog file target in async, while serilog isn't configured to use async.

If I change the Serilog config to use Serilog.Sinks.Async version 1.3:
.WriteTo.Async(a => a.File("Log.txt"), blockWhenFull: true) // blockWhenFull is true, because NLog is also configured to block when full.
then I get the following results:
