Need to be able to specify dispose:true

[danielabbatt]

I tried to use this in a console application but found that if I logged and exited immediately then the log file was not flushed, there was no opportunity to specify the dispose.
I ended up doing the below in the end.

// Set up Serilog
Log.Logger = new LoggerConfiguration()
	.WriteTo.RollingFile(logFilename)
        .CreateLogger();

// Add logging
services.AddSingleton(
	new LoggerFactory()
		.AddSerilog(dispose:true)
		.AddConsole(loggingConfiguration)
		.AddDebug(LogLevel.Trace)
);

Thanks for the heads-up, Daniel. I think dispose: true should be the default/only supported option using this package - if you or anyone out there would like to investigate and/or send a PR, any help here would be appreciated. Thanks!

I had a similar problem that I could not access the log file despite disposing the logger factory.

I first tried this (not working):

using var loggerFactory = LoggerFactory.Create(builder =>
{
    builder.AddFile(path to file);
});

I was then digging around the .NET source code and found this and this.

The code in the first link is called when using the ILoggingBuilder extension methods. I don't know why but disposing: false is enforced there, so my first code snipped could not work.

The code in the second link is called when using the ILoggerFactory extension methods. Here, disposing: true is enforced.

With these findings I changed the code to:

using var loggerFactory = LoggerFactory.Create(builder => { });
loggerFactory.AddFile(path to file);

And now everything is working fine. When the method finishes, the file handle is disposed properly.
