I am trying to create a folder and a text file in a MAUI project. When I run the application, I receive the following message:
Base Directory: C:UsersxyzAppDataLocal
Log Directory: C:UsersxyzAppDataLocalTestLogs
Log File Path: C:UsersxyzAppDataLocalTestLogstestlogfile.txt
Test file created successfully.
However, the folder TestLogs and file testlogfile.txt are not actually created. How can I resolve this issue?

Here is the content of MauiProgram.cs:

using System;
using System.IO;
using Microsoft.Maui;
using Microsoft.Maui.Hosting;

namespace Hexe
{
    public static class MauiProgram
    {
        public static MauiApp CreateMauiApp()
        {
            var builder = MauiApp.CreateBuilder();
            builder
                .UseMauiApp<App>()
                .ConfigureFonts(fonts =>
                {
                    fonts.AddFont("OpenSans-Regular.ttf", "OpenSansRegular");
                    fonts.AddFont("OpenSans-Semibold.ttf", "OpenSansSemibold");
                });

            // Ermitteln des Pfads zum Stammverzeichnis der Anwendung
            string baseDir = Environment.GetFolderPath(Environment.SpecialFolder.LocalApplicationData);
            string logDir = Path.Combine(baseDir, "TestLogs");
            string logFilePath = Path.Combine(logDir, "testlogfile.txt");

            // Debug-Ausgabe des Pfads
            System.Diagnostics.Debug.WriteLine($"Base Directory: {baseDir}");
            System.Diagnostics.Debug.WriteLine($"Log Directory: {logDir}");
            System.Diagnostics.Debug.WriteLine($"Log File Path: {logFilePath}");

            // Erstellen des TestLogs-Ordners, falls nicht vorhanden
            try
            {
                if (!Directory.Exists(logDir))
                {
                    System.Diagnostics.Debug.WriteLine("Creating TestLogs directory...");
                    Directory.CreateDirectory(logDir);
                }

                // Test-Datei schreiben
                File.WriteAllText(logFilePath, "Dies ist ein Testeintrag, um die Datei- und Ordnererstellung zu überprüfen.");
                System.Diagnostics.Debug.WriteLine("Test file created successfully.");
            }
            catch (Exception ex)
            {
                System.Diagnostics.Debug.WriteLine($"Error creating test file: {ex.Message}");
            }

            return builder.Build();
        }
    }
}

The development environment is Visual Studio.
