Hi, I want to program a UWP app, where I read the metadata of music files. I have included taglip and in a normal program the code work but in the app he didnt work.
Here is the Code, the error is on this part.
"Dim Musikdatei As TagLib.File = TagLib.File.Create(Datei.Path)"

Dim folder As StorageFolder
Private Async Sub menuItem_Open_Explorer()
Dim ordnerAuswählen = New Pickers.FolderPicker()
ordnerAuswählen.SuggestedStartLocation = Pickers.PickerLocationId.Desktop
ordnerAuswählen.FileTypeFilter.Add("*")
folder = Await ordnerAuswählen.PickSingleFolderAsync()
txtOrdner.Text = folder.Path
End Sub

Private Async Sub Button_Click(sender As Object, e As RoutedEventArgs)
Dim titel, Interpret, Jahr As String
Dim Dateienliste As IReadOnlyList(Of StorageFile)
Dateienliste = Await folder.CreateFileQuery(1).GetFilesAsync()
For Each Datei As StorageFile In Dateienliste

Dim Musikdatei As TagLib.File = TagLib.File.Create(Datei.Path)

titel = Musikdatei.Tag.Track

lblDateien.Items.Add(Datei.Name)

Next
End Sub
End Class

This is the error message
An Exception Typ "System.UnauthorizedAccessException" is in taglib-sharp.dll occurred, but this was not processed in user code.
Is there a solution for this? Or can't I use the library in apps?
