KeyNotFoundException in Track.Delete when using SpotifyLib as references project

[ChrisBrandhorst]

Error:

• Track.Delete throws a System.Collections.Generic.KeyNotFoundException at line 121

Steps to reproduce:

• Having some project which references SpotifyLib as a project in the solution (unlike referencing the SpotiFire.SpotifyLib.dll)
• Start a session and login (triggers the capture of playlists)

Somehow the error does not occur when I reference the .dll instead of the project.

Fix:

• Add if (! tracks.ContainsKey(trackPtr)) return; between line 120 and 121

I don't really see how the collection could miss the track-pointer unless it was mutated somewhere, are you able to debug it to see if the track-pointer is actually added to the dict?

Fixed in my branch (see pull request).

The Track that was disposed was not a Track, but a PlaylistTrack. Since PlaylistTrackWrapper did not have its own OnDispose method, the TrackWrapper.OnDisposed was used, resulting in a call to Track.Delete (which of course failed, since PlaylistTracks are stored in a seperate Dictionary).

For this to work, I needed to add public get properties Position and Playlist to PlaylistTrack.
