Flush on shutdown

Other logging frameworks have different ways of telling the framework that the application is about to shut down. This is great for batching and/or async loggers since it will give them a chance to flush their buffered log message.

Example from Serilog:

Log.CloseAndFlush();

Example from NLog:

LogManager.Shutdown();

I cannot seem to find a similar feature of Microsoft.Extensions.Logging. I know that providers indirectly implement IDisposable but Dispose doesn’t seem to be consistently called on shutdown.

Is there any way of detecting that an application is about to shut down or would it be possible to implement support for this in Microsoft.Extensions.Logging?

Yep 😄 !

That’s a good point 😂 I guess this would be the way to go?

var services = new ServiceCollection();
services.AddLogging(logging => logging.AddBlaBla(...));
var serviceProvider = services.BuildServiceProvider();
var loggerFactory = serviceProvider.GetService<ILoggerFactory>();
var logger = loggerFactory.CreateLogger("mylogger");
// Do some logging
serviceProvider.Dispose();
