Hello,
after my first web based project, now i created a comparing tool in .net
the Apploication is a helper to check if episodes missing.
you add the API key and hit (1. Read Plex),
it compares the Plex Library by selecting it (2. this can cost a moment
than you have a highlighted list,
Red text = Series ended.
Green background = episode count matching with thetvdb count.
you can select a series-name an see detailed episode / season list and all episodes from the plex server.
all you need to know is how to get your API KEY
