There used to be a hosted sample app at https://woodgrovegroceriesb2c.azurewebsites.net/, but the sample app/website is no longer there. It was nice to be able to see what Azure B2C does out of the box. Is there a hosted sample app anywhere else?
Try:
https://woodgrovegroceriesb2cdemo.azurewebsites.net/
The old site seems to have been taken down.
