[severity:It's more difficult to complete my work]
I have create a .net core 3.1 API project and am hosting this in a Windows Service (windows 10 latest).

When I start my project from Visual Studio, my API runs as a console application and performs the configured API functionality and logging without problem. When I register that same .exe as a windows service, the service will not start. When I remove serilog configuration from the Main method in Program.cs file, the windows service starts and works as expected. Specifically, when I comment out the line "var config = builder. Build();" and republish the project, my service will start normally. Any help would be much appreciated.

public static void Main(string[] args)
{
var builder = new ConfigurationBuilder();
BuildConfig(builder);
var config = builder. Build();
string logdbPath = Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData) + @"\EPDAPI\log.db";

Log.Logger = new LoggerConfiguration()
. ReadFrom.Configuration(config)
. Enrich.FromLogContext()
. WriteTo.SQLite(logdbPath)
. CreateLogger();

Log.Logger.Information("Application Starting");

EnableDapperCustomTypeHandlers();

CreateHostBuilder(args)
. UseWindowsService()
. UseSerilog()
. Build()
. Run();

}

public static IHostBuilder CreateHostBuilder(string[] args)
{
return Host.CreateDefaultBuilder(args)
. ConfigureServices((context, services) =>
{
services. AddSingleton<ISQLiteDataAccess, SQLiteDataAccess>();
services. AddSingleton<IContactData, ContactData>();
services. Configure(context. Configuration.GetSection("Kestrel"));
})

. ConfigureWebHostDefaults(webBuilder =>
{
webBuilder.ConfigureKestrel(serverOptions =>
{
// Set properties and call methods on options
})
. UseStartup();
});

}

static void BuildConfig(IConfigurationBuilder builder)
{
builder. SetBasePath(Directory.GetCurrentDirectory())
. AddJsonFile("appsettings.json", optional: false, reloadOnChange: true)
. AddJsonFile($"appsettings.{ Environment.GetEnvironmentVariable("ASPNETCORE_ENVIRONMENT") ?? "Production"}.json", optional: true)
. AddEnvironmentVariables();
}

my appsettings.json file contains a small section on serilog

"Serilog": {
"MinimumLevel": "Information",
"Override": {
"Microsoft": "Information",
"System": "Warning"
}
},

Thanks for contacting us.
This would be a good question to ask to the serilog community.
That said, this most probably is an issue with the identity (which the Windows service is running under) not having enough permissions. When you start the app yourself, it runs under your own user account which obviously does have the necessary rights.
