I hate .NET and I have been fighting with this for weeks. Some of the problems I encountered;

1. a faulty pair of API Keys, they just didn't work. I guess it was a random bug.
2. I also have a couple MP4's that I downloaded from Youtube that would not upload back, within creator studio they would say "Upload failed: Can't process file" I determined this by attempting to upload them in the youTube interface. (not through API)
3. async vs. synchronous was causing me many issues I just don't understand.

I would like to improve this code to provide actual upload status/feedback but I think that would need to be done client side. I am not very good at C#/.NET

UPDATE here is my feedback code via server & client side - https://stackoverflow.com/a/49516167/3790921
