Hallo,
diesesmal mit dem 2ten Anlauf, und auch im richtigen Forum.
Diese Version funktioniert komplet.
Ich möchte diese aber nochmal hier posten bevor ich mich an Detrails mache: Linq,Und solche Geschichten wie : ReleaseYear in ReleaseDate umbennenen und das dann als Time und nicht als int..,Save(),Load()
