A manager for a speedy async saving objects to isolated storage, using serialization from Newtonsoft.Json. A project to play with is here. ``` public static async Task ReadJsonEx(String filepath) { if (String.IsNullOrEmpty(filepath)) return default(T); return await await Task.Factory.StartNew(async () => { using (var store = IsolatedStorageFile.GetUserStoreForApplication()) using (var stream = new IsolatedStorageFileStream(filepath, FileMode.Open, store)) using (var sr = new StreamReader(stream)) using (var jr = new JsonTextReader(sr)) return await jr.ReadJsonAsyncTask(); }); } public static async Task WriteJsonEx(String filepath, T content) { if (String.IsNullOrEmpty(filepath)) return false; return await await Task.Factory.StartNew(async () => { using (var store = IsolatedStorageFile.GetUserStoreForApplication()) using (var stream = new IsolatedStorageFileStream(filepath, FileMode.Create, store)) using (var sw = new StreamWriter(stream)) using (var jw = new JsonTextWriter(sw)) await jw.WriteJsonAsyncTask(content); return true; }); } ``` Where extensions are ``` private static readonly JsonSerializer JsonSerializer = new JsonSerializer { NullValueHandling = NullValueHandling.Ignore, MissingMemberHandling = MissingMemberHandling.Ignore }; public static async Task WriteJsonAsyncTask(this JsonTextWriter writer, T content) { writer.Formatting = Formatting.Indented; return await TaskEx.Run(() => { try { JsonSerializer.Serialize(writer, content); } catch (Exception) { return false; } return true; }); } public static async Task ReadJsonAsyncTask(this JsonTextReader reader) { return await TaskEx.Run(() => JsonSerializer.Deseria
