I have a WinForms .NET 4.8 Visual Studio ClickOnce application that uses VideoLAN.LibVLC.Windows and LibVLCSharp.Winforms NuGet packages.

After updating to the latest versions (3.0.20 and 3.8.5) of these libraries from NuGet, I found that the libvlc directory (and contents) are not installed on the client PC. The libvlc directory and contents are published to the server by Visual Studio during the Build/Publish process. Upon installation on the client PC, the libvlc directory is not copied from the server to the client PC. Previously, it was copied to the client PC. I have updated VLC versions periodically for the last couple of years without problem.

Before updating, the NuGet versions were 3.0.18 and 3.7.0.
