What is the best way to go about reading and writing simple configuration data like we used to use App.config and Web.config
available thr
LocalSettings
http://msdn.microsoft.com/en-us/library/windows/apps/windows.storage.applicationdata.localsettings
OR
RoamingSettings
http://msdn.microsoft.com/en-us/library/windows/apps/windows.storage.applicationdata.roamingsettings.aspx
The main difference is that RoamingSettings will be saved to the cloud and thus, can be transferred across different devices for the same user profile. LocalSettings is device-specific.
