Thanks for getting this started @duffh. I just have few suggestions.

I think how you have it now works too. Only suggesting:

• projection necessary
• nameof() syntax
• unnecessary TaskCanceledException catch
• unnecessary Stop when Start is about to be called again
• if double tapped gesture is needed, we can still call Stop there

Looks good 👍 thanks for staying on top of deprecation warnings :)
