Persistent Storage in Windows Phone 7
- by Richard Jones
Mark Arteaga – fellow MVP just helped me with this,  thought I’d share.     Windows Phone 7 SilverLight supports persistent storage, which is a great way of saving settings betweens runs of your application.  However I couldn’t get it to work.  If you do this to create a persistant storage instance -     private IsolatedStorageSettings userSettings =   IsolatedStorageSettings.ApplicationSettings;   To retrieve settings do the following -   string xx = userSettings[“SomeValue”].ToString();     Hiowever the bit that got me was how to save settings, you have todo this -   userSettings.Add("Hello", DateTime.Now.ToShortTimeString());             userSettings.Save(); // <- This is the bit that got me     Hope this helps others
