      You have to give credit to Hanselman as well he is the best at preventing not to know anything when in fact he is probably as knowledgeable as Stephen.

    When I say that I have watched every video and read every article about async and await, I am not exaggerating. However not a single one has come close to educating what this does, why and how to use it and how this is implemented as this does. This is one of the best videos I have seen on this subject.
    I would love to see more videos like this, that deep dive into the technical rather than floating around at surface level

However I have one small nitpick, that of Stephen constantly making the font way too small to read. Scott kept picking him up on it, but it's really important for us who are watching to be able the read the code that they're writing and thus for presenters to realise how video tutorials need zoomed up fonts.

Take some modern c# code and replace all the syntactic sugar with the underlying implementations. And/Or show how you can look up the underlying implementations quickly & easily.
