using Microsoft.Extensions.FileProviders;
using Microsoft.Extensions.FileProviders.Physical;
using var provider = new PhysicalFileProvider(AppContext.BaseDirectory);
Environment.SetEnvironmentVariable("DOTNET_USE_POLLING_FILE_WATCHER", "1");
var contents = provider.GetDirectoryContents(string.Empty);
foreach (PhysicalFileInfo fileInfo in contents)
{
Console.WriteLine(fileInfo.PhysicalPath);
}
var changeToken = provider.Watch("*.txt");
changeToken.RegisterChangeCallback(_ => Console.WriteLine("Text file changed"), null);
Console.ReadLine();
