Index Out of Range Exception When Disposing Many Viewers At Once

[Nickprovs]

I have an issue about Vlc.DotNet.

Generic information

• Vlc.DotNet version : 3.0.0
• Vlc.DotNet project used : (WPF)
• libvlc version : 3.0.8.0 - x64 + From VLC Media Player Directory
• .net version : 4.5.2
• Project language : C#
• Project build architecture : AnyCPU
• Operating system : Windows 10 x64

Summary

Launched 6-9 (no joke -- that's just the range I tested) RTMP streams in a grid. Then, on button press -- dispose of them. This exception seems to intermittently occur.

• [ X] I confirm that my issue doesn't happen in VLC itself.

If I add a lock around the work done with the myInteropDelegates dictionary in VLCLibraryLoader -- I don't get the exception anymore. I believe that because I'm opening many streams at once -- the insertions are happening too quickly on different threads and the dictionary's internal array is not resizing properly.

If I do this -- I no longer get this issue.
