When I attempt to upload logs from our application, we execute the following code to get all the log files on the device:

    public static string NLogDefaultPath = Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments) + "/logs/";

    /// <returns></returns>
    public async Task<IEnumerable<string>> FetchLogsAsync()
    {
        var logFiles = Directory.GetFiles(AppConstants.NLogDefaultPath);

        var logs = new List<string>();

        foreach (var log in logFiles)
        {
            logs.Add(await File.ReadAllTextAsync(log));
        }

        return logs;
    }

I test in a scenario where I did some logged events in the app on 05/29/2024. I shut down the app at the end of the day. I then started the app up in the morning (5/30/2024) on the device and performed more logged events. I then attempted to upload the log files. When the above code ran, it only found 1 file and that file contained the logged events from 5/29/2024. I did a few more things in the app and kept testing over the next hour or so. Then after an hour or so, the above code found another log file, it was uploaded and it contained the logged events for 5/30/2024. I am trying to figure out why there was a delay in the above code seeing the second log file. This is a huge issue as when we are attempting to trouble shoot issue in production we are often getting log files that do not cover the period of time the issue occurred. I ensured I am running all the latest NLog nuget packages. The device is running Android 11 and the app is created using .Net Maui 8. Any information would be greatly appreciated.

When following the instructions in the Readme, the target is not recognized by the xsd schema:

What am I missing?

using
Nlog 5.1.1
Nlog.Targets.MauiLog 1.0.2

Hi
can you provide working example how to use that library with MAUI application. How to access logs?
Exist similar project https://github.com/jfversluis/MauiMetroLogSample but it another library. I would prefer to use Nlog

Cache directory (Returns the LocalCacheFolder directory)

FileSystem.Current.CacheDirectory;

C:/Users/{MyName}/AppData/Local/Packages/{GUID}_{hash}/LocalCache/

App data directory (Returns the LocalFolder directory that is backed up to the cloud)

FileSystem.Current.AppDataDirectory;

C:/Users/{MyName}/AppData/Local/Packages/{GUID}_{hash}/LocalState/

For NetStandard (and others) then it can just return:

System.AppContext.BaseDirectory

https://docs.microsoft.com/en-us/dotnet/maui/platform-integration/storage/file-system-helpers?tabs=windows

Notice MAUI performs virtualization so when resolving SpecialFolder.LocalApplicationData then it automatically redirect to custom folder:

C:/Users/{MyName}/AppData/Local/Packages/{GUID}_{hash}/LocalCache/

Xamarin.iOS will not load the MauiLog Target unless the following is added somewhere in the iOS portion of the solution.
[assembly: Preserve(typeof(NLog.Targets.AppleOSLogTarget), AllMembers = true)]

This should either be put in AppleOSLogTarget directly or should be noted in the readme.

AppVeyor-file is ready, so just need the last push

NLog.Targets.Xamarin is now replaced by NLog.Targets.MauiLog, since Xamarin will reach end-of-life at May 1, 2024

Where do I get the log file from android phone? Does it need to config to specific path to get the log file? Or does it just log to the output only?

I'm using the NLog MAUI library v5.2.0 for debugging my MAUI Android and iOS application created using Visual studio.
I'm not using a file and instead I'm using write to MAUI log. I can see the Android logs I've added in the device logs through logcat.
However on an iOS device i don't see the logs I've added in the device logs. Nor do I see them in the console. I've tried checking the boxes for debug and info logs in the console actions as well. Where can I see these logs on iOS.

I've tried using this target in my application but it appears do be doing nothing at all.
I then tried to run the example application - no logs in logcat
I then checked the example app for any log calls - there are none.

Has this target been tested at all yet?

Possible to update the owner to include NLogLogging for the nuget-package:
