in order to debug on Series 6/7 simulators (Pretty much Xcode 11+) you need to change the watchOS app arch to x86_64 from the project settings

very old issue but still valid i think today. I am not sure if I understand the answer from @dalexsoto Ui seems to be different on the latest VS for Mac. what is the suggested solution here?

Closing, since watchOS isn't supported in .NET, and Xamarin is not supported anymore.
