I'm using Virtual Box V6.1.14 with Guest Additions on an Win10-64 Host hosting a Win10-64-Virtual machine.
In the Virtual-Box-Client I want a .NET-FileSystemWatcher-Object (.Net Framework 4.8) to notify when a file in some folder changes.
Im the Virtual machine this works well in case of
However, when I share a Folder from the host-machine via the VirtualBox-GUI-Option "Shared Folders" I cannot watch it and get a Win32Exception: "Unzulässige Funktion" (just have a german windows) with HR = -2147467259 (0x80004005)
Anyone knows what this means and more important: On what kind of folders this may happen too?
Is there a solution to that other than polling the directoy via a Timer?
