How would I go about implementing a feedback function on a windows phone 7 app? I've considered creating a form that sends an email with the data to an address I own, but I wonder if there is a better solution.
I personally think the simplest and best solution is to use EmailComposeTask to send the feedback via email.
You could either just put some questions/suggested text in the Body - or you could fill the Body in with some information from a SL form.
One of the advantages of the EmailComposeTask is you will definitely get their email address to reply to. Another advantage is that the feedback will work even when there isn't currently a network connection - it'll just get added to the outbox for later processing.
