it helps some times I'm making a project for windows phone 8 using C# and I want to be able to save some strings to storage so the next time the user opens the app, He'll be able to have the strings he saved last time he opened it.
code :
if (IsolatedStorageSettings.ApplicationSettings.Contains("key") && 
        IsolatedStorageSettings.ApplicationSettings["key"] != null)
    string GetKey = IsolatedStorageSettings.ApplicationSettings["key"].ToString();

will be helpful for those in need .Save() actually persists the isolated storage settings instance (such as ApplicationSettings) to the media (e.g. phone storage).
This is automatically done when your application is tombestoned (_Deactivated) or closed (_Closed). That is why you get same value without even calling save.

I wish did fix the issue. You can't serialize a private class in the ApplicationSettings. Declare it as public instead:
code :
public class LyricsItem
    public LyricsItem()


    public LyricsItem(LyricsItem item)
        this.searchUrl = item.searchUrl;
        this.croppingRegex = item.croppingRegex;

    private string _searchUrl;
    private string _croppingRegex;

    public string searchUrl
        get { return _searchUrl; }
        set { _searchUrl = value; }

    public string croppingRegex
        get { return _croppingRegex; }
        set { _croppingRegex = value; }

This might help you I've managed to find the implementation of the IsolatedStorageSettings.Save method in the entrails of the Windows Phone emulator VHD images supplied with the Windows Phone SDK (the answer to this question on SO helped me to do that). Here is the source code of the method:
code :
public void Save()
    lock (this.m_lock)
        using (IsolatedStorageFileStream isolatedStorageFileStream = this._appStore.OpenFile(this.LocalSettingsPath, 4))
            using (MemoryStream memoryStream = new MemoryStream())
                Dictionary<Type, bool> dictionary = new Dictionary<Type, bool>();
                StringBuilder stringBuilder = new StringBuilder();
                using (Dictionary<string, object>.ValueCollection.Enumerator enumerator = this._settings.get_Values().GetEnumerator())
                    while (enumerator.MoveNext())
                        object current = enumerator.get_Current();
                        if (current != null)
                            Type type = current.GetType();
                            if (!type.get_IsPrimitive() && type != typeof(string))
                                dictionary.set_Item(type, true);
                                if (stringBuilder.get_Length() > 0)
                byte[] bytes = Encoding.get_UTF8().GetBytes(stringBuilder.ToString());
                memoryStream.Write(bytes, 0, bytes.Length);
                DataContractSerializer dataContractSerializer = new DataContractSerializer(typeof(Dictionary<string, object>), dictionary.get_Keys());
                dataContractSerializer.WriteObject(memoryStream, this._settings);
                if (memoryStream.get_Length() > this._appStore.get_AvailableFreeSpace() + isolatedStorageFileStream.get_Length())
                    throw new IsolatedStorageException(Resx.GetString("IsolatedStorageSettings_NotEnoughSpace"));
                byte[] array = memoryStream.ToArray();
                isolatedStorageFileStream.Write(array, 0, array.Length);

this one helps. If you are saving ONLY when the app is closing (i.e. Application_Closing), then you are not capturing the state often enough. Depending upon how you have exited the app, there are times when the application is simply deactivated, but not necessarily closed. If the app is subsequently tombstoned after deactivation, you will have needed to save the state appropriately to restore it back.
Here is an article to give you a better idea of the different states.
