Windows Phone 8.1 - Isolated Storage

Question

I was just wondering how you deal with IsolatedStorageSettings in Windows Phone 8.1 SDK. For Example:

IsolatedStorageSettings.ApplicationSettings.Contains("LocationConsent")

How does this work in 8.1? As in, how do I write this statement without getting context errors. I feel like it's been deprecated or something because it does not resolve to a known namespace or anything.

I am working with maps for my current project and porting it to 8.1 gives me some syntax trouble. I have tried looking it up but I think it's too soon for documentation I guess because MSDN doesn't even say anything about it, unless I missed it by accident. Any help is appreciated.

Use the classes in Windows.Storage namespace. They are new for Universal Apps. If you want the data to stay always local try Windows.Storage.ApplicationData.Current.LocalSettings. However, if you wouldn't mind them been stored in roaming settings (they would be available for your app in Windows 8.1 in case you do Universal Apps) you can use Windows.Storage.ApplicationData.Current.RoamingSettings.

var localSettings = Windows.Storage.ApplicationData.Current.LocalSettings;
if(localSettings.Values.ContainsKey("LocationConsent"))
   DoSomething(localSettings.Values["LocationConsent"])

or

var roamingSettings = Windows.Storage.ApplicationData.Current.RoamingSettings;
if(roamingSettings.Values.ContainsKey("LocationConsent"))
   DoSomething(roamingSettings.Values["LocationConsent"])

This should resolve your issue. I wrote this from the top of my head, hopefully it will work for you.
