    Could you post a transcript in English? This is the first time I've been unable to understand the words of a Channel 9 show.

    I believe AWS has translation capability - and this would also help with indexing the videos with search engines.

    Just turn on closed captions (CC). It works ok.

    Thanks Bruce - using YouTube with CC does get me captions.

    I generally download the highest quality MP4 and watch using VLC - but for some reason, I can't get captions to work - the .vtt file loads, but ... no matter how I change the settings, no captions show up.

    But, there's so much detail in many of the Channel 9 segments I watch, it would still be rather cool to have a pdf transcript as I could highlight the important concepts in yellow or green to make it easy to reference the video at a later time.

    We're currently using EF6 with migrations. Will there be any way to port that to EF Core?
