For a Windows Phone 8 application, I always heard that data can be stored in the "isolated storage" of the phone.
After some research, I found two namespaces: LocalStorage (WinRT but supported too in WinPRT) and IsolatedStorage and they both seem to store data. This is what I understood so far :
In the IsolatedStorage, can data from various apps mix ?
I want a way to have a real safe isolated place to store data with no extenal interaction from other apps. This data could be settings preferences.
The problem is that I do not know very well those APIs and my testing programs
around them lead to new questions.
What is the real difference between those namespaces and which one could fulfill my need explained above ?
Both APIs are used to manipulate with an app file system and there is no a restriction for media files. The main difference between these two APIs is that
IsolatedStorage type is available just for Windows Phone applications and
ApplicationData type is available for Windows Phone applications as well as for Metro Windows 8 applications. So, if you are going to develop your app for both platforms: Windows Phone 8 and Windows 8, I would suggest you to use
ApplicationData API, so you can have a common services assembly that is used in both your projects, in WP8 and in Win8 too.
On the other hand, both APIs are completely safe. That's mean no any other application can access to the file system of your application.
But if you are going to develop an application for WP7.8 and WP8 then you have no choice and have to use
