These are the files after doing the 10 days of Xamarin course at https://10daysofxamarin.blog/
It's all basically cut and pasted from the blog at the moment - but it works. At least, it works using the Android simulator.
There is a list of existing 'Experiences' which you can't really do anything with at the moment, so I might try and extend it so that you can see the ones that have gone before. Also you can't edit.
