I'm trying to create a single file executable for my console application. The problem is that logging files are not created for some reason. If I run application in Visual studios, simple debug mode then everything works fine, I can see log file appear in the \bin\Debug\netcoreapp3.1 folder.

This is what publishing settings I use

I am using NLog for logging, and that's how my code looks regarding that

services.AddLogging(builder =>
{
    builder.SetMinimumLevel(Microsoft.Extensions.Logging.LogLevel.Trace);
    builder.AddNLog("nlog.config");
});
LogManager.Configuration = new NLogLoggingConfiguration(config.GetSection("NLog"));

and thats appsettings.json where I hold my nlog configurations

        "targets": {
            "console": {
                "type": "ColoredConsole",

CodePudding user response：

Found the solution after hours and hours of struggle. so my allLog.txt file path was "fileName": "${basedir}/logs/allLog.txt", apparently if one file executable is created ${basedir} will become something into like C:\Users\my_username\AppData\Local\Temp\.net\my_project_name\VnUDuP7f4QxGtrsSuaNaBXA_wxhYftr=\ , so to fix that I need to use ${basedir:fixtempdir=true} instead of ${basedir} so full path would be ${basedir:fixtempdir=true}/logs/allLog.txt.
