which exactly native librairies for a WPF Platform do I need from NuGet? For the moment I installed those (see picture please) but It seems that I miss another one. Have someone an idea?
You have to also install VideoLAN.LibVLC.Windows
nuget package and build the solution.
Probably you do not need LibVLCSharp.Forms.* nugets. They contain support for Xamarin.Forms.
