I’m writing a Windows Phone 7 app and am looking for a way to get a unique and unchanging device Id that I can use to identify the device and therefore the user (since Microsoft doesn’t give you access to the users Windows Live Id). Anyone know if this is going to be possible? Especially interested to find out if the id will be a) unique and b) unchanging.
Thanks,
There is an anonymous live ID (ANID) rather than having direct access to the windows live ID. There is also a unique device ID. Further detail and code samples here for your reference.
