.NET (C#) Roon Api implementation

I will use the api in a uwp Project to use the Surface dial

After

  private async void MainPage1_Loading(FrameworkElement sender, object args)
    {
        await DiscoverCore();

I got following exception

System.IO.FileNotFoundException: “Could not load file or assembly ‘System.Security.Permissions, Version=4.0.1.0, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51’. Das System kann die angegebene Datei nicht finden.”

Nuget deliver only v4.4.0

After Install

System.IO.FileLoadException: “Could not load file or assembly ‘System.Security.Permissions, Version=4.0.1.0, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51’. The located assembly’s manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)”

Can you help ?
