Hi,
I have a app that should assign a unique number to the device, on which app is installed. So, whenever the app is used, even after many days , it should get that unique ID for the device and extract all the information related to it from the database.
For the unique ID I am have tried creating GUID using System.Guid.NewGuid().
I have two questions,
1. Is there a way of getting GUID assigned using System.Guid function?
2.I want to store it permanently to the app, it should be stored until the app is uninstalled. Which option of system storage should I use?
Thanks in advance for the help.
P.S. I want it to work for phone as well as tab.
