Write a c# demo project that create a local folder that links to remote OneDrive folder.

using Microsoft.SharePoint.Client;
using System;
using System.IO;
using System.Text;

class Program
{
static void Main(string[] args)
{
// Specify the local folder path.
string localFolderPath = @"C:\Temp\MyFolder";

// Specify the SharePoint site URL.
string sharePointSiteUrl = "https://your-sharepoint-site-url.com";

// Specify the SharePoint document library name.
string documentLibraryName = "Shared Documents";

try
{
// Create the local folder if it doesn't exist.
if (!Directory.Exists(localFolderPath))
{
Directory.CreateDirectory(localFolderPath);
Console.WriteLine("Local folder created successfully.");
}
else
{
Console.WriteLine("Local folder already exists.");
}

// Get the URL of the SharePoint document library.
string documentLibraryUrl = GetSharePointDocumentLibraryUrl(sharePointSiteUrl, documentLibraryName);

// Create a shortcut file (.url) that points to the SharePoint document library.
CreateShortcutFile(localFolderPath, documentLibraryUrl);

Console.WriteLine("Shortcut file created successfully.");
}
catch (Exception ex)
{
Console.WriteLine($"An error occurred: {ex.Message}");
}

Console.ReadLine();
}

static void CreateShortcutFile(string folderPath, string targetUrl)
{
// Create the shortcut file (.url) content.
StringBuilder shortcutContent = new StringBuilder();
shortcutContent.AppendLine("[InternetShortcut]");
shortcutContent.AppendLine($"URL={targetUrl}");

// Create the shortcut file in the local folder.
string shortcutFilePath = Path.Combine(folderPath, "Shortcut.url");
File.WriteAllText(shortcutFilePath, shortcutContent.ToString());
}

static string GetSharePointDocumentLibraryUrl(string siteUrl, string documentLibraryName)
{
using (ClientContext context = new ClientContext(siteUrl))
{
// Authenticate to SharePoint (add authentication code if necessary).

// Load the web and lists.
Web web = context.Web;
context.Load(web, w => w.ServerRelativeUrl);
context.Load(web.Lists, lists => lists.Include(l => l.Title, l => l.RootFolder.ServerRelativeUrl));
context.ExecuteQuery();

// Find the document library by name.
List documentLibrary = web.Lists.FirstOrDefault(list => list.Title == documentLibraryName);

if (documentLibrary != null)
{
// Construct the document library URL.
string documentLibraryUrl = $"{siteUrl}{documentLibrary.RootFolder.ServerRelativeUrl}";
return documentLibraryUrl;
}
else
{
throw new Exception("Document library not found.");
}
}
}
}

Above code is written using chatgpt.
Need an working example and to create a SharePoint test side.

So task :
* Create a working c# program
* Create a test SharePoint site
* Make the program use the test site. Making it possible to work with the site as if it was a local folder.
